Aw-68, HLA class I histocompatibility antigen, A-28 alpha chain, MHC class I antigen A*68, HLA-A, MHC class I antigen HLA A heavy chain
Major histocompatibility complex (MHC) molecules form an integral part of the immune response system. They are cell-surface receptors that bind peptides and present them to T lymphocytes. HLA-A, -B and -C encode membrane anchored heavy chains which heterodimerize with a light chain (b-2-Microglobulin) to form MHC-I. Polymorphisms yield hundreds of HLA-A, -B and -C alleles.
