STRUCTURE OF THE HUMAN CLASS I HISTOCOMPATIBILITY ANTIGEN, HLA-A2
Contents |
Overview
The class I histocompatibility antigen from human cell membranes has two structural motifs: the membrane-proximal end of the glycoprotein contains two domains with immunoglobulin-folds that are paired in a novel manner, and the region distal from the membrane is a platform of eight antiparallel beta-strands topped by alpha-helices. A large groove between the alpha-helices provides a binding site for processed foreign antigens. An unknown 'antigen' is found in this site in crystals of purified HLA-A2.
Disease
Known diseases associated with this structure: Abacavir hypersensitivity, susceptibility to OMIM:[142800], Ankylosing spondylitis, susceptibility to, 1 OMIM:[142800], Hypoproteinemia, hypercatabolic OMIM:[109700], Stevens-Johnson syndrome, susceptibility to OMIM:[142800]
About this Structure
