MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a serum protein found in association with the major histocompatibility complex (MHC) class I heavy chain on the surface of nearly all nucleated cells. The protein has a predominantly beta-pleated sheet structure that can form amyloid fibrils in some pathological conditions. The encoded antimicrobial protein displays antibacterial activity in amniotic fluid. A mutation in this gene has been shown to result in hypercatabolic hypoproteinemia.[provided by RefSeq, Aug 2014]
PHENOTYPE: Homozygotes lacking B2m appear normal, but have no detectable MHC class I antigen on their cells and are deficient in CD4- CD8+ T cells which mediate cytotoxic T cell function. Mutant mice are also subject to systemic iron loading. [provided by MGI curators]
