R I E T H M Ü L L E R Received November 1,1985 • Accepted November 14,1985 Abstract A m o n g the numerous autoimmune diseases associated with various H L A alleles, the one w i t h the highest relative risk so far reported has been ankylosing spondylitis w i t h H L A - B 2 7 . To examine this relationship more directly, we have cloned the gene encoding the H L A - B 2 7 antigen and determined its complete D N A sequence. Comparison of the H L A - B 2 7 sequence w i t h that of the allelic H L A - B 7 shows a high level of homology. Mutations are distributed evenly between exons and introns. Exon 1 and intron 1 are the most divergent ones, and the degree of divergence distinctly declines towards the 3' end. The H L A - B 2 7 gene when transfected into murine L cells is expressed on the cell surface and reacts with a panel of monoclonal antibodies directed against monomorphic and polymorphic determinants associated with H L A - B 2 7 antigen. The isolation of this gene allows for the first time a search for structural features which make the H L A - B 2 7 antigen a high risk genetic factor for a group of rheumatoid disorders, in particular ankylosing spondylitis. Introduction Among the numerous H L A markers associated with various human diseases, the H L A - B 2 7 antigen is a clear exception. This allelic glycoprotein, present in the cell membrane of all nucleated cells, represents an unusually high-risk factor for its carriers, conveying susceptibility for a group of joint diseases of which ankylosing spondylitis (AS) is the most prominent. Pooling all data on Caucasians, one arrives at a relative risk of more than 70.0 for individuals carrying the H L A - B 2 7 antigen (1). Recent Abbreviations: AS = ankylosing spondylitis; bp = base pair; kb = kilo bases; mAb = monoclonal antibody; T = cytotoxic T cell; tk = thymidine kinase. c 368 • ELISABETH H . WEISS, W . K U O N , C . DÖRNER, M . L A N G , and G . RIETHMÜLLER studies have been directed towards elucidating the biochemical structure of the H L A - B 2 7 antigen (2, 3). So far, no differences between the H L A - B 2 7 antigens present in healthy and AS patients have been found. Even the subdivision of H L A - B 2 7 into several antigen subtypes (4) did not indicate any structural differences between the H L A - B 2 7 molecules from healthy and affected individuals. In order to investigate the mechanisms of H L A involvement in disease, in general, and the nature of the H L A - B 2 7 and AS association in particular, we isolated the gene encoding the H L A - B 2 7 antigen. In this paper we describe the expression of the H L A - B 2 7 gene in murine L-cells and present the complete D N A sequence of the gene encoding the H L A - B 2 7 polypeptide together with its deduced complete amino acid sequence. The genomic organization of the H L A - B 2 7 gene is compared with a cross-reactive allele, the homologue H L A - B 7 gene, which exhibits no significant disease association. Materials and Methods Isolation of the HLA-B27 gene A genomic library was constructed w i t h the vector p T C F (5, 6 ) from peripheral white blood cells of a healthy individual with the H L A type: H L A - A 2 / 2 , -B5/27, -Cw2/3. The cosmid library was screened w i t h an H L A - B locus specific c D N A probe derived from the 3'untranslated region of the H L A - B 8 gene (7). DNA sequence analysis D N A sequence analysis of the three B g l l l fragments containing the entire H L A - B 2 7 gene subcloned in the vector p U C l 3 was carried out mostly by the dideoxy sequencing method (8) and partly, to verify ambiguous nucleotides, by the chemical sequencing procedure (9). The sequencing strategy is shown in Figure 1. Transfection of cosmid clone CD2.6 into murine Ltk~ cells Murine thymidine kinase negative (tk~) cells, L D l ( H - 2 ) were transformed with cosmid D N A and the herpes tk gene contained in the vector p O P F (5), using the calcium phosphatemediated D N A transfer technique (10). Populations of transformed cells were selected using hypoxanthine-aminopterin-thymidine ( H A T ) selection, and stable L t k transformed clones were established. The human lymphoblastoid cell line L G - 2 ( H L A - A 2 , 2 ; B27/27; Cwl/1) was used as a positive control for H L A - B 2 7 expression. k + Monoclonal antibodies (mAb) The origin and characteristics of the mAbs used are listed in Table 1.

RIETHMÜLLER Results Genomic organization of the HLA-B27 gene The entire H L A - B 2 7 gene is contained in the cosmid clone C D 2.6. The restriction map of the cosmid clone and the gene, itself contained in three B g l l l fragments, is shown in Figure 1. No other class I gene was located within a distance of 6 kb to the left side and of 30 kb to the right side of the H L A - B 2 7 locus. Since this cosmid clone contains only one H L A class I gene, it was used directly for the gene transfer experiments. Expression of the human HLA-B27 antigen in murine cells transformed with the cloned HLA-B27 gene (CD2.6) We have introduced cosmid C D 2.6 (see Fig. 1) together with the herpes simplex virus thymidinekinase (tk) gene into mouse L tk~ (of H - 2 haplotype) cells using calcium phosphate D N A transfer.

The results of the binding assays are shown in Figure 2 and Table 2. All clones derived from the CD2.6 transformation bind anti-HLA class I monomorphic antibody (W6/32) at a level comparable with the endogenous H-2 antigen expression. The level of H L A antigen detected was 30-50 % of that of the H - 2 antigen. These assays demonstrate that L cells transformed with cosmid CD2.6 expressed a cell-surface polypeptide which is recognized by W6/32, while the untransformed cells were completely negative. To characterize the HLA-antigen encoded by the clone CD2.6 we used several monoclonal reagents directed against H L A antigens of the donor from whom the cosmid library was constructed (see Table 2). The H L A - A 2 allele was excluded, since the monomorphic anti-HLA-A monoclonal antibody, K T l , and monoclonal antibody MA2.1, which reacts with H L A - A 2 , did not bind to the transfectant clones (or gave signals comparable to the M P C l l control). The cosmid clone CD2.6 did bind, however, two monoclonal k 372 • ELISABETH H . WEISS, W . K U O N , C. D Ö R N E R , M . L A N G , and G . RIETHMÜLLER antibodies directed against HLA-B27. The reagent M E l binds to the transfectants at the same level as W6/32. This binding is not due to crossreactivity with H L A - B 7 , since binding of BB7.1 was negative. The monoclonal antibody B27.M2, which recognizes a subset of H L A - B 2 7 antigens, also binds to the transfectant clones, although at a much lower level. This reagent is strongly positive for a B cell line derived from the individual from whom CD2.6 was isolated. The lower binding of this mAb to the transfected L cell may be due to the combination of xenogeneic ß microglobulin with the H L A - B 2 7 polypeptide. The expression of transfected H L A - B 2 7 gene in the murine cells is increased twofold after incubation with lymphognes present in a supernatant derived from rat spleen cells stimulated with Concanavalin A (data not shown). These data show that cell lines transformed with cosmid CD2.6 express a cell-surface antigen with a specificity which is indistinguishable from the H L A - B 2 7 antigen of the positive control B cell line L G - 2 (HLA-A2,2; B27/27). We therefore conclude that the clone CD2.6 codes for the H L A - B 2 7 antigen. We tried to determine whether the presence of the H L A - B 2 7 molecule on the murine cells could render these cells as targets for allogeneic cytotoxic T cell ( T cell)-mediated killing by human T cells raised against the H L A - B 2 7 antigen. Thus far, however, human anti-B27 T cells did not lyse the transfectant L cell clones significantly (data not shown). It was reported previously that murine L cells expressing H L A class I genes are poor targets for human allogeneic T cells (11, 12), whereas other transfected murine cells expressing H L A class I antigens can be lysed by human allogeneic T cells (12). 2 c c c c c General structure of the HLA-B27 gene The overall structure and dimensions of the H L A - B 2 7 gene are the same as those of other reported H L A genes. The H L A - B 2 7 gene consists of eight exons and seven introns. Table 3 shows that the majority of the exons are of the same length as those of the H L A - B 7 (14) and H L A - A 2 (14, 15) genes. The sequence of cloned H L A - B 2 7 c D N A derived from the L G 2 line, which we reported recently, confirms these exon assignments (16). The approximate size of the introns is the same in all three genes, with only minor variations in the exact lengths. DNA sequence of the HLA-B27 gene We determined the D N A sequence of the entire H L A - B 2 7 gene. The sequencing strategy is shown in Figure 1. The complete D N A sequence together with the deduced amino acid sequence of the HLA-B27 antigen is shown in Figure 3. The sequence of the H L A - B 2 7 gene is similar to that of other human class I genes reported earlier (14-19). For the first time, determination of the exact length of exon 1 could be made from the sequence of this H L A - Organization and Expression of the H L A - B 2 7 Gene • 373 Table 3.

All other H L A class I genes published to date contain two in frame initiation codons (see Fig. 4) which would result in two possible leader peptides of 21 and 24 amino acids. HLA-B27 contains only the first A T G with an exon 1 of 49 base pairs. The gene contains the 3.5 kb Taq I fragment, a previously described restriction fragment length polymorphism which was assigned to the H L A - B 2 7 gene (27). The fragment was detected by using an H L A class I c D N A probe. The Taq I fragment spans the 3' half of the H L A - B 2 7 gene. The detection of this HLA-B27-specific gene band becomes easier when a probe derived directly from this region or an H L A B locus specific probe is used. Potential Alternative Splicing Signals in the HLA-B27 gene. Recently, an alternative intron/exon organization affecting the second exon has been proposed for the H - 2 K gene (28). In a c D N A clone, apparently derived from a processed H - 2 K transcript, an alternative splice acceptor site in the first intron, 50 nucleotides 5' to the usual acceptor site, is used. In addition, an extra intron is created by the splicing out of a D N A segment of exon 2, coding for the amino acids 6-38 of the classical H - 2 K antigen. Until now it could not be shown whether this alternative splice site is used in vivo yielding a polypeptide that is synthesized from this alternative m R N A transcript. d d d

Nucleotide sequence of the H L A - B 2 7 gene. Nucleotides are numbered from the Sac I site. The promotor ( T C T A A A ) and the polyadenylation ( A A T A A A ) signals are underlined. Splice sites and potential alternative splice signals are indicated by lines. The amino acids are placed above the triplets of he exons in the three letter code. Organization and Expression of the H L A - B 2 7 Gene • 375 Inspection of the H L A - B 2 7 gene sequence reveals several alternative splice sites (AG/G) only a few of which do not result in stop codons. The alternative splice acceptor sites described for the H - 2 K gene are found in exactly the same positions in the H L A - B 2 7 gene (659 and 831, marked in Fig. 3) together with the corresponding donor site in exon 2 at position 736. The additional exon would code for 26 amino acids as in the H - 2 K gene. A similar alternative transcript cannot be generated from the H L A - B 7 gene. The presence of potential alternative splice signals in the H L A - B 2 7 gene raises the question of whether they might be used. No c D N A clone coding for H L A - B 2 7 has been described that is the product of an alternative spliced transcript (16). d d A complete c D N A sequence coding for the H L A - B 2 7 antigen (16) and potential peptide sequencing data for this antigen (3) have been published recently. We, therefore, do not discuss the protein sequence in detail. It is of interest to note that the genomic sequence for the H L A - B 2 7 antigen contains the triplet G C G at amino acid position 182 coding for alanine, as it was found by protein sequencing (3). The c D N A clones, derived from a homozygous B cell line, code for a valine ( G T G ) in this position. A second amino acid replacement change is found in the leader at amino acid position 7 where the c D N A clone codes for a glutamine ( G A G ) , due to a change of three nucleotides. Another additional nucleotide is found in the 3'untranslated region at position 3692. The insertion of a T destroys the Taq I site found in the c D N A (16). This Taq I site is in so far important, because the L G 2 line from which the c D N A clones were derived cannot contain the polymorphic Taq I fragment of 3.5 kb. Its corresponding fragment must be of 1800 bp. The five changes are the only differences found between the c D N A sequence and the genomic D N A sequence. Since both genes code for the same H L A - B 2 7 subtype (HLA-B27.1), we conclude that this might be the first evidence for somatic mutations in B cell lines in a gene other than immunoglobulin. Comparison of the gene sequence of HLA-B27 with an allelic gene sequence. The comparison of the two H L A - B alleles, H L A - B 2 7 and the crossreactive H L A - B 7 , at the gene level shows a high degree of nucleotide sequence conservation in both coding (exons) and non-coding regions (introns), as well as in the flanking regions (Table 3). The highest level of divergence is expressed in intron 1 and exon 1, which is not contained in the mature H L A molecule. The degree of divergence is highest in the 5' half of the gene (exon 1 to exon 3). The H L A - B 2 7 and H L A - B 7 genes are virtually identical in the 3'part of the genes. Surprisingly, the exons and introns have accumulated mutations to a similar degree. The sequence comparison of exon 2 of the two alleles (Fig. 4) reveals that most of the mutations are scattered. Only one cluster of changes is found to the 3' end of this exon, from amino acid position 77 to 83.

The amino acids are shown in the three letter code. | Organization and Expression of the H L A - B 2 7 Gene • 377 Discussion We have shown that the cosmid clone CD2.6 contains one H L A class I gene which is the H L A - B 2 7 gene. This human H L A gene can be expressed in murine L cells and is recognized by monoclonal anti-HLA reagents even when the heavy chain is combined with murine ß microglobulin. Several monoclonal antibodies demonstrate that the epitopes, normally associated with the H L A - B 2 7 molecule, are present on the surface of the transformed L cells. The D N A sequence and deduced amino acid sequence of the H L A - B 2 7 antigen were compared to the D N A sequence of its allele H L A - B 7 . As we have discussed elsewhere (16), the polypeptide structure exhibits some replacement changes unique to the H L A - B 2 7 antigen. Among them two mutations are unusual: position 67 is occupied by a cysteine and position 131 by a serine. The change in position 131 generates a new restriction site, G A G C T C , which is recognized by the enzyme Sacl. These changes could be decisive in the peculiar role of H L A - B 2 7 as a risk factor for ankylosing spondylitis. Surprisingly, the comparison of the D N A structure of the H L A - B 2 7 gene with its allele H L A - B 7 revealed a high degree of homology between the two genes. This is interesting in two aspects: Firstly, the HLA-B27/B7 pair is another example of human class I alleles showing a greater degree of nucleotide conservation than allelic class I genes in the mouse (15, 29). Thus, the two murine alleles H - 2 K and H - 2 K have a much lower level of homology in the polymorphic exons 2 and 3 (10.3 and 11.2% divergence, respectively), whereas the introns show the same degree of homology as the human alleles (see Table 3). This higher mutation rate in the H - 2 K genes could be due to their position centrometric to the I-A region, thus possibly making it a preferred target for gene conversion events. This explanation is supported by the sequences of H-2 class I genes other than H-2K. The sequence comparison of the H - 2 D gene with its proposed allele H - 2 L (30) ( H - 2 D being less homologous) shows a level of divergence comparable to human H L A - A and H L A - B alleles. Another explanation for the fact that the human class I alleles are more similar than their murine homologues could be based on the different evolution in the two species. It remains to be explained why human class I alleles exhibit quite a high degree of divergence at the 5' half of the gene (exon 1 and intron 1). The second aspect of interest concerns the differences found between the H L A - B 2 7 and H L A - B 7 genes. The two H L A - B alleles are as homologous as the H L A - A alleles and show to the 3'end of the gene, i.e. exon 4 to 3' untranslated region, an even higher level of homology. This fact makes it difficult to assign the cause for the association of H L A - B 2 7 with certain diseases to particular structural features of the H L A - B 2 7 gene. Surprisingly, the highest degree of divergence is found in exon 1 and intron 2. The leader peptide, encoded by exon 1, is cleaved off during maturation of the 2 b b d d d 378 • ELISABETH H . WEISS, W . K U O N , C . DÖRNER, M . L A N G , and G . RIETHMÜLLER H L A class I molecule. The sequence of intron 2 is not part of the mRNA and therefore not translated. Only in case of an alternative processed transcript of the HLA-B27 gene involving intron 2 could this sequence be of importance. Several hypotheses have been proposed to explain the association of some H L A alleles with certain diseases. The isolation and expression of the gene encoding the H L A - B 2 7 antigen allows us to address the proposed mechanism with recombinant D N A techniques. Since we isolated the gene from a so far healthy individual, we cannot rule out the highly unlikely possibility that the H L A - B 2 7 gene of a patient might contain mutations. T R A P A N I et al. (31) isolated a 3.5 kb Taq I fragment containing the 3'half of a supposed H L A - B 2 7 gene from a spondylitic patient. The partial sequence of 180 bps, derived from intron 6-exon 7-intron 7 presented in this report, is identical to our sequence, except the G at position 3223 in intron 7 is lacking in their sequence but is contained in the H L A - B 7 gene. To examine the possibility that a putative «illness susceptibility» gene in linkage disequilibrium with H L A - B 2 7 is responsible for the diseases associated with this antigen (the two-gene theory; see ref. 1 for review) we have begun chromosomal walking experiments starting from the HLA-B27 gene, in order to compare the organization of the H L A - B 2 7 haplotype with other extended H L A - B loci. The molecular mimicry hypothesis (the one-gene theory; see ref. 1 for review) postulates that the molecular structure of infectious agents are similar to those of the H L A antigens on the cell surface. In vitro mutagenesis experiments may be helpful in defining HLA-B27 specific epitopes that may cross-react with bacterial proteins. At present, we are converting the H L A - B 2 7 unique replacement changes at amino acid positions 67 and 131 back to the «wildtype» configuration. Then we can analyze whether these mutations affect the overall structure of the molecule defined by monoclonal antibodies and human allogeneic cytotoxic T cells. In summary, this paper describes the isolation of the H L A - B 2 7 gene which, for the first time, allows the investigation of the mechanisms underlying the observed association between HLA-B27 and various diseases.
