H2-T3 - histocompatibility 2, T region locus 3

Predicted to enable several functions, including 14-3-3 protein binding activity; TAP binding activity; and signaling receptor binding activity. Predicted to be involved in several processes, including antigen processing and presentation of endogenous peptide antigen via MHC class I via ER pathway, TAP-independent; antigen processing and presentation of endogenous peptide antigen via MHC class Ib; and positive regulation of T cell mediated cytotoxicity. Predicted to be located in several cellular components, including Golgi apparatus; bounding membrane of organelle; and endoplasmic reticulum exit site. Predicted to be part of MHC class I peptide loading complex; MHC class I protein complex; and MHC class Ib protein complex. Predicted to be active in external side of plasma membrane and extracellular space. Is expressed in small intestine and thymus. Human ortholog(s) of this gene implicated in several diseases, including asthma (multiple); autoimmune disease (multiple); eye disease (multiple); human immunodeficiency virus infectious 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).
