Wikipedia β2 microglobulin also known as B2M is a component of MHC class I molecules, MHC class I molecules have α 1, α 2, and α 3 proteins which are present on all nucleated cells (excludes red blood cells). In humans, the β 2 microglobulin protein is encoded by the B2M gene. Beta-2-microglobulin (β 2 -microglobulin) is a component of major histocompatibility complex (MHC) class I molecules that is present on all nucleated cells (excluding red blood cells). 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.

β2-microglobulin (β2M) is a 12 kD nonpolymorphic Ig like protein. It is a non-membrane-anchored glycoprotein and is noncovalently associated with 39-44 kD polymorphic heavy chains of MHC class I molecules to form HLA class I antigen complex.

Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Exogenously applied Mar 1, 1998 Human β2m (hβ2m) binds to murine MHC I molecules with higher affinity Peptide and β2-microglobulin regulation of cell surface MHC class I 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.

Los niveles normales de gama beta-2 microglobulina 1 a 2,1 microgramos por mililitro (g / ml); valores de rango normales superiores son 2,0 a 2,5 mg / ml. Una molécula de MHC de clase I consiste en dos cadenas de polipéptidos, una cadena alfa largo de la izquierda y una cadena más corta a la derecha que es beta-2 microglobulina. Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states.

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. β2 microglobulin also known as B2M is a component of MHC class I molecules, MHC class I molecules have α 1, α 2, and α 3 proteins which are present on all nucleated cells (excludes red blood cells).

B2M alone (not in complex with HLA-I) interacts with M.tuberculosis EsxA (ESAT-6) and an EsxA-EsxB (CFP-10) complex; the tripartite complex can be Structure of A6-T cell receptor bound to MHC class I molecule complexed with an altered Htlv-1 Tax Peptide Y8a. The HIV peptide is shown in gray. MHC class I molecule is in dark blue, the associated beta 2 microglobulin in light blue. T cell receptor is in green and yellow. Y. Description. β2-microglobulin (β2M) is a 12 kD nonpolymorphic Ig like protein. It is a non-membrane-anchored glycoprotein and is noncovalently associated with 39-44 kD polymorphic heavy chains of MHC class I molecules to form HLA class I antigen complex.

Meanwhile, the CD8 co-receptor of CD8 T-cell would interact with α3. β2M: Beta 2 microglobulin; MHC I: Major histocompatibility complex class I; CD8: Cluster of differentiation 8. The MHC class I molecule is a heterodimer composed of an integral membrane glycoprotein designated the α chain and a non-covalently associated, soluble protein called beta 2-micro-globulin (β 2 m). Loss of β 2 m generally eliminates antigen recognition by antitumor CD8 + T cells. β-2-microglobulin (β2-M) is a polypeptide that associates with the heavy chain of class I major histocompatibility complex (MHC) antigens on the cell surface. The interaction is dynamic and plays a critical role in the stability of the MHC antigens and their ability to present peptide antigens in CD8+ cells.Proteins are used in routine laboratory procedures such as binding enzymes or Beta 2-Microglobulin β2-microglobulin was first isolated by Bergard and Bearn ( J Biol Chem 243:4095, 1968 ) from the urine of patients with cadmium-induced renal tubular damage.

Beta-2-microglobulin (Beta2m) constitutes the 12kDa light chain of the class I major histocompatibility complex (MHC-I) on the surface of many cells, to which it is Beta-2 microglobulin (B2M) is a component of MHC class I system. B2M associates with MHC class I α chain, CD1 and Qa. Loss of B2M function causes iron Interaction of calnexin (CNX) with MHC class I HC stabilizes it and facilitates the association of the beta2 microglobulin component (B2M).

About B2M / Beta 2 Microglobulin: Beta-2-Microglobulin (also known as β2M) is a Protein Coding gene. Beta 2 microglobulin is found in almost all nucleated cells and most biological fluids, including serum, urine, and synovial fluid, it is a small protein (11,800 Dalton) that's critical for the immune surveillance and modulation in vertebrate animals.

It forms the light chain subunit of the MHC class I antigen. Beta 2 microglobulin is an 11 kDa protein associated with the outer membrane of many cells including lymphocytes. It is the small subunit of the MHC class I molecule.
