Description
Predicted to enable MHC class II protein complex binding activity. Predicted to be involved in antigen processing and presentation of exogenous peptide antigen via MHC class II; peptide antigen assembly with MHC class II protein complex; and positive regulation of T cell activation. Predicted to act upstream of or within several processes, including MyD88-dependent toll-like receptor signaling pathway; negative regulation of innate immune response; and negative regulation of toll-like receptor signaling pathway. Predicted to be located in extracellular region and membrane. Predicted to be integral component of membrane. Predicted to be part of MHC class II protein complex. Is expressed in several structures, including eye; heart; integument; liver; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in arthritis; familial visceral amyloidosis; immunodeficiency 43; and inflammatory bowel disease. Orthologous to human B2M (beta-2-microglobulin).
