Predicted to enable several functions, including 14-3-3 protein binding activity; TAP binding activity; and signaling receptor binding activity. Acts upstream of or within female pregnancy. Predicted to be located in several cellular components, including bounding membrane of organelle; cell surface; and endoplasmic reticulum. Predicted to be part of 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 brain; small intestine; and thymus. 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-E (major histocompatibility complex, class I, E); HLA-F (major histocompatibility complex, class I, F); and HLA-G (major histocompatibility complex, class I, G).
