Beta 2-Microglobulin (b2M)
β2 microglobulin also known as B2M is a component of MHC class I molecules, which are present on all nucleated cells (but not red blood cells). β2 microglobulin lies lateral to the α3 chain on the cell surface. Unlike α3, β2 has no transmembrane region. Directly above β2 lies the α1 chain, which itself is lateral to the α2. β2 microglobulin associates not only with the alpha chain of MHC class I molecules, but also with class I-like molecules such as CD1 and Qa.
The complete amino acid sequence of the beta-2-microglobulin protein. It is a single polypeptide chain with a molecular mass of 11.6 kD that shows homology to immunoglobulins and HLA, suggesting a common evolutionary origin.
