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 excess. [1] For more details, see: Human beta two microglobulin.
 DiseaseElevated B2M levels are found in patients of liver chirossis. RelevanceB2M is used as a marker for certain types of blood cell cancer. It can indicate the spread and severity of myeloma. Structural HighlightsHuman β-2 microglobulin with MHC class I HLA-A2 and HCMV PP65 nonapeptide (3mrb).
