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] Human beta two microglobulin .
Diagram of MHC I Complex
Disease Elevated B2M levels are found in patients of liver cirhossis.
Relevance B2M is used as a marker for certain types of blood cell cancer. It can indicate the spread and severity of myeloma.
