B2m - beta-2 microglobulin

Predicted to enable MHC class II protein complex binding activity and protein homodimerization activity. Involved in response to cadmium ion and response to xenobiotic stimulus. Located in extracellular space. Biomarker of acute kidney failure; pyelonephritis; and ureteral obstruction. 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).
