Beta 2 microglobulina mhc

Beta-2-microglobulin (β2m) is the light chain of the major histocompatibility complex (MHC) class I cell surface heterodimer. β2m is well conserved across most species with few polymorphisms seen within species. The aims of this study were to clone and express ovine β2m and investigate if allelic variation of ovine β2m exists.

They are involved in the discrimination of self from non-self. 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. Clinical Information Beta-2-microglobulin (beta-2-M) is a small membrane protein (11,800 Dalton) associated with the heavy chains of class I major histocompatibility complex proteins and is, therefore, on the surface of all nucleated cells.

A beta-2 microglobulin test is usually a blood test, but may also be given as a 24-hour urine test, or as a cerebrospinal fluid (CSF) analysis. For a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. Beta-2-microglobulin 在β 2 的“上方”（指远离细胞膜的一端）为α链的α 1 区和α 2 区，构成了MHC的肽结合区。 Beta-2 microglobulin (beta2m) is a globular protein that self-associates into fibrillar amyloid deposits in patients undergoing hemodialysis therapy. Formation of these beta-sheet-rich assemblies is a fundamental property of polypeptides that can be triggered by diverse conditions. Binding of the ligand activates the cytolytic response of natural killer (NK) cells, CD8 alphabeta T cells, and gammadelta T cells which express the receptor. This protein is stress-induced and is similar to MHC class I molecules; however, it does not associate with beta-2-microglobulin or bind peptides.

Human beta 2 Microglobulin associated with HLA Class I antigens are expressed on many types of cells including lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells, and epithelial cells, but is absent on erythrocytes. 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 the beta-chain of major histocompatibility complex class I molecules.
