Beta-2 microglobulin from human urine
Store at +4°C short term (1-2 weeks). Aliquot and store at -20°C long term. Avoid repeated freeze/thaw cycles.
This gene encodes a serum protein found in association with the major histocompatibility complex 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.B2M is a Protein Coding gene. Diseases associated with B2M include Immunodeficiency 43 and Amyloidosis, Familial Visceral. Among its related pathways are Cytokine Signaling in Immune system and Innate Immune System. Gene Ontology annotations related to this gene include identical protein binding.Component of the class I major histocompatibility complex. Involved in the presentation of peptide antigens to the immune system. Exogenously applied M.tuberculosis EsxA or EsxA-EsxB binds B2M and decreases its export to the cell surface, probably leading to defects in class I antigen presentation.
