Supplementary information

Beta-2 microglobulin (B2M) is a component of the major histocompatibility complex (MHC) class I molecules which are integral to the immune system. It is also associated with the neonatal Fc receptor (FCGRT or FcRn). The B2M protein has a mass of approximately 11.8 kDa. This protein is widely expressed with notable expression in all nucleated cells. In humans the role of B2M includes antigen presentation to T cells and it aids in the stabilization of MHC molecules.
Biological function summary

B2M interacts with the neonatal Fc receptor and is involved in the regulation of IgG antibody levels by extending their half-life. As part of the FcRn complex B2M also aids in the transport of IgG across epithelial barriers such as the intestinal lining in neonatal mammals. This complex plays a significant role in maintaining the homeostasis of IgG antibodies therefore impacting adaptive immunity.

Pathways

B2M participates in antigen processing and presentation. It forms a complex with FCGRT which is critical in the FcRn pathway responsible for the recycling and transcytosis of immunoglobulins. This interaction preserves IgG from lysosomal degradation. Additionally B2M interacts with other proteins like albumin through related pathways highlighting its involvement in protein recycling and homeostasis.

B2M is relevant to several autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. Altered B2M levels are indicative of these conditions reflecting immune dysregulation. Higher levels of B2M are also observed in multiple myeloma a disorder featuring malignancies of plasma cells. In these disease contexts B2M often serves as a biomarker alongside elevated levels of IgG or the presence of paraproteins.
