STRUCTURE OF THE HUMAN CLASS I HISTOCOMPATIBILITY ANTIGEN, HLA-A2
|
OverviewOverview
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.
