Protein name

HLA class I histocompatibility antigen, B-48 alpha chain

Comment

FUNCTION:Involved in the presentation of foreign antigens to the immune system.||SUBUNIT:Heterodimer of an alpha chain and a beta chain (beta-2- microglobulin). Interacts with human herpesvirus 8 MIR1 protein (By similarity).||SUBCELLULAR LOCATION:Membrane; Single-pass type I membrane protein.||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).||POLYMORPHISM:The following alleles of B-48 are known:B*48:01 and B*48:03. The sequence shown is that of B*48:01.||SIMILARITY:Belongs to the MHC class I family.||SIMILARITY:Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
