Summary: Enables peptide antigen binding activity. Acts upstream of or within several processes, including antigen processing and presentation of endogenous peptide antigen via MHC class I via ER pathway, TAP-dependent; antigen processing and presentation of exogenous peptide antigen via MHC class I; and positive regulation of T cell mediated cytotoxicity. Located in external side of plasma membrane. Is expressed in several structures, including brain; genitourinary system; hemolymphoid system gland; liver; and retina. Used to study myositis. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); asthma (multiple); autoimmune disease (multiple); eye disease (multiple); and inner ear disease (multiple). Orthologous to several human genes including HLA-A (major histocompatibility complex, class I, A); HLA-B (major histocompatibility complex, class I, B); and HLA-C (major histocompatibility complex, class I, C).

Major histocompatibility class I molecules H2-Kb and H2-Db proteins regulate sculpting of local cortical circuits and in their absence, the excess connectivity can function as a substrate for cortical plasticity throughout life.

Title: Adopting the rapamycin trapping assay to track the trafficking of murine MHC class I alleles, H-2K(b).
Because all forms of H-2K(b) are internalized but little beta2m-receptive heavy chain is present at the cell surface, it is likely that beta2m dissociation and recognition of the heavy chain for lysosomal degradation take place in an endocytic compartment.

Major histocompatibility class Ib-restricted CD8-positive T cells, in addition to H2-M3-restricted T cells, contribute to antilisterial immunity and may contribute to immune responses against other intracellular bacteria.
Title: Nonconventional CD8+ T cell responses to Listeria infection in mice lacking MHC class Ia and H2-M3.
The interaction of SHIP, 2B4 activating receptor, and the major histocompatibility complex influence the regulation of the natural killer (NK) cell receptor repertoire, cytolytic function, and interferon-gamma production.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
