GeneID: 3105 Human HLA-A

Swiss-port # P30443 Human HLA class I histocompatibility antigen, A-1 alpha chain

Gene Symbol HLA-A
Gene Full Name major histocompatibility complex, class I, A
Background HLA-A2 (44 kDa) is the most frequent HLA-A allele in human ethnic populations. HLA-A, together with HLA-B and HLA-C, represent human HLA class I major histocompatibility (MHC) antigens. These intrinsic membrane glycoproteins are expressed on nucleated cells and noncovalently associate with an invariant beta2 microglobulin. They carry foreign determinants important for immune recognition by cytotoxic T cells, thus important for anti-viral and anti-tumour defence._x000D_
Function Involved in the presentation of foreign antigens to the immune system. [UniProt]
Research Area Immune System antibody
Calculated MW 40 kDa
PTM Polyubiquitinated in a post ER compartment by interaction with human herpesvirus 8 MIR1 protein. This targets the protein for rapid degradation via the ubiquitin system (By similarity).
