- Description
- Predicted to enable MHC class II protein complex binding activity and peptide antigen binding activity. Predicted to be involved in several processes, including 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 antigen processing and presentation of peptide antigen via MHC class I and immune response. Predicted to be located in extracellular region. Predicted to be part of MHC class II protein complex. Predicted to be active in late endosome membrane and lysosomal membrane. Is expressed in several structures, including eye; heart; integument; liver; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in arthritis; immunodeficiency 43; and inflammatory bowel disease. Orthologous to human B2M (beta-2-microglobulin).
