Enables
beta-2-microglobulin binding activity and peptide binding activity. Involved in T cell tolerance induction; negative regulation of natural killer cell mediated cytotoxicity; and positive regulation of adaptive immune response based on somatic recombination of immune receptors built from immunoglobulin superfamily domains. Used to study graft-versus-host disease. Human ortholog(s) of this gene implicated in several diseases, including Stevens-Johnson syndrome; asthma (multiple); autoimmune disease (multiple); eye disease (multiple); and inner ear disease (multiple). Orthologous to several human genes including HLA-B (major histocompatibility complex, class I, B); HLA-C (major histocompatibility complex, class I, C); and HLA-F (major histocompatibility complex, class I, F); PARTICIPATES IN allograft rejection pathway; antigen processing and presentation pathway; autoimmune thyroiditis pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; acetamide; ammonium acetate.
