Description

BCMA (B cell maturation antigen), is a single-pass, type III transmembrane glycoprotein in the TNF receptor superfamily (TNFRSF17). BCMA contains a short extracellular domain (ECD) of 84 amino acid (aa), containing one TNFR cysteine-rich repeat. Within the TNFRSF, it shares the highest homology with TACI (TNFRSF13B). Both BCMA and TACI have been shown to bind to APRIL (TNFSF13) and BAFF (TNFSF13B), members of the TNF ligand superfamily. BCMA is expressed in immune organs and mature B cells, but not in T-cells or monocytes. BCMA is located on the cell surface and also found in a perinulear Golgi-like structure.  The binding of BCMA to APRIL or BAFF has been shown to stimulate IgM production in peripheral blood B cells and increase the survival of B cells, suggesting that BCMA may play an important role in B cell development,  function and regulation. BCMA lacks a death domain (DD) in the cystoplasmic region.  BCMA interacts with various TNFR-associated factors (TRAFs), including TRAF1, TRAF2 and TRAF3, to transduce signals for B cell survival and proliferation. Overexpression of BCMA activates NF-κB and JNK signaling pathways. A chromosomal aberration in BCMA is found in a form of T-cell acute lymphoblastic leukemia (T-ALL).
