The human leukocyte antigen (HLA) alleles HLA-B*2704 and HLA-B*2706 show an ethnically restricted distribution and are differentially associated with ankylosing spondylitis, with HLA-B*2706 lacking association with this autoimmune disease. However, the products of the two alleles differ by only two amino acids, at heavy-chain residues 114 (His in H...

The product of the human leukocyte antigen (HLA) gene HLA-B*2704 differs from that of the prototypical subtype HLA-B*2705 by three amino acids at heavy-chain residues 77 (Ser instead of Asp), 152 (Glu instead of Val) and 211 (Gly instead of Ala). In contrast to the ubiquitous HLA-B*2705 subtype, HLA-B*2704 occurs only in orientals. Both subtypes ar...

The product of the human leukocyte antigen (HLA) gene HLA-B*2703 differs from that of the prototypical subtype HLA-B*2705 by a single amino acid at heavy-chain residue 59 that is involved in anchoring the peptide N-terminus within the A pocket of the molecule. Two B*2703-peptide complexes were crystallized using the hanging-drop vapour-diffusion me...

... Biomacromolecular crystallography. Protein preparation, crystallization, and x-ray data collection, as well as phasing of B*27:04 and B*27:06 in complex with pVIPR, have previously been described in detail (16,17). Following molecular replacement, the initial 2F o -F c electron density maps revealed the presence of the nonapeptide when inspected with the software Coot (18). ...

... There are two important characteristic structures which are different from others: the presence of B pocket and the free thiol group of Cys67. [6,7] According to the latest Immuno Polymorphism Database-ImMuno GeneTics/HLA (IPD-IMGT/HLA) database, there are about 161 subtypes of HLA B*27:01 to HLA B*27:161. [8] There is a variable distribution of HLA-B27 gene among world population, with the highest prevalence in northern territory of the earth. ...
