Beta 2-microglobulin (b2-m) is an 11-kDa protein recognized as the light-chain component of the MHC-I molecule. It is produced by nucleated cells membranes and is detectable in the serum and other body fluids. The link between the b2-m/ MHC-1 molecules and membrane structure has been associated with lymphocyte activation. NX_P61769 - B2M - Beta-2-microglobulin - Function.

Functional MHC class I molecules are expressed on the cell surface in the absence of beta(2)-microglobulin (beta(2)m) light chain that can interact with CD8(+) T lymphocytes. Whether their assembly requires peptide binding and whether their recognition by CD8(+) T lymphocytes involves the presentation of peptide epitopes remains unknown.

Beta-2 microglobuline is een component van de MHC klasse 1 antigenen. Het is aanwezig op alle gekernde cellen en wordt bijna volledig gereabsorbeerd door de proximale tubuli. Het is een merker voor immuunactivatie en voor de werking van de proximale tubulus.

Exogenously applied We demonstrate that exogenous β2-microglobulin (β2m) stabilizes human cell surface MHC I molecules and facilitates their loading with exogenous peptides. Intracellular assembly of MHC class I heavy chains with β2-microglobulin occurs prior to the expression of the antigen-presenting complex on the cell surface. Interaction of calnexin (CNX) with MHC class I HC stabilizes it and facilitates the association of the beta2 microglobulin component (B2M). The two chains are It is the small subunit of the MHC class I molecule. Association with beta 2- microglobulin is generally required for the transport of class I heavy chains from the Native beta-2 microglobulin is a component of MHC class I molecules, which are present on all nucleated cells.

Los marcadores tumorales son sustancias producidas por las células cancerosas o por las células normales en … La β 2 microglobulina nota anche come B2M è un componente delle molecole MHC di classe I, le molecole MHC di classe I hanno proteine α 1, α 2 e α 3 che sono presenti su tutte le cellule nucleate (esclusi i globuli rossi). Negli esseri umani, la proteina β 2 microglobulina è codificata dal gene B2M. Beta-2 microglobulin is a cell membrane protein, exists in a protein complex termed MHC-1 (HLA in humans). During an immune response, MHC proteins, as well as Beta-2 microglobulin levels, increase.

In humans, the β 2 -microglobulin protein is encoded by the B2M gene. MHC class I molecules and beta(2)-microglobulin (beta(2)m) are membrane glycoproteins that present peptide Ags to TCRs, and bind to inhibitory and activating receptors on NK cells and other leukocytes. They are involved in the discrimination of self from non-self. Modification of these molecules in … Feb 18, 2021 · Beta-2 microglobulin (b2m) is a naturally occurring protein in the human body.
