products description :
Beta 2-microglobulin is the low molecular weight component of HLA antigens and as such is involved in the presentation of endogenous antigens, activation of T lymphocytes and functional emergence of natural killer cells. It is found in the serum of normal individuals and in the urine in elevated amounts in patients with Wilson disease, cadmium poisoning and other conditions leading renal tubular dysfunction.

ncbi summary :
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]
uniprot summary :
B2M: Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Heterodimer of an alpha chain and a beta chain. Beta-2- microglobulin is the beta-chain of major histocompatibility complex class I molecules. Polymers of beta 2-microglobulin can be found in tissues from patients on long-term hemodialysis. Belongs to the beta-2-microglobulin family. Protein type: Secreted; Secreted, signal peptide. Chromosomal Location of Human Ortholog: 15q21.1. Cellular Component: Golgi membrane; Golgi apparatus; extracellular space; phagocytic vesicle membrane; focal adhesion; membrane; endoplasmic reticulum lumen; early endosome membrane; cytoplasm; plasma membrane; extracellular region; MHC class I protein complex; external side of plasma membrane. Molecular Function: identical protein binding; protein binding. Biological Process: response to drug; regulation of immune response; viral reproduction; positive regulation of T cell mediated cytotoxicity; cytokine and chemokine mediated signaling pathway; antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-independent; T cell differentiation in the thymus; antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-dependent; regulation of defense response to virus by virus; retinal homeostasis; antigen processing and presentation of peptide antigen via MHC class I; iron ion homeostasis; response to cadmium ion; response to molecule of bacterial origin; innate immune response; antigen processing and presentation of exogenous peptide antigen via MHC class I; protein refolding; antigen processing and presentation of exogenous protein antigen via MHC class Ib, TAP-dependent. Disease: Hypoproteinemia, Hypercatabolic
