Background: BCMA/TNFRSF17

BCMA, B cell maturation antigen, also known as Tumor Necrosis Factor Receptor Superfamily member 17 (gene name TNSFR17), is a member of the TNFR superfamily, due to the presence of its TNFR motif (1). BCMA is a type III membrane protein containing one extracellular cysteine rich domain, a transmembrane domain, and an intracellular domain. Within the TNFRSF, it shares the highest homology with TACI. BCMA and TACI have both been shown to bind to APRIL and BAFF, members of the TNF ligand superfamily (2, 3). This binding to APRIL and BAFF has been shown to stimulate IgM production in peripheral B cells and increase the survival of cultured B cells (3, 4). This data suggests that BCMA may play an important role in B cell development, function, and regulation (5). BCMA expression has been found in immune organs and mature B cell lines (5). Although some expression has been observed at the cell surface, BCMA appears to be localized to the Golgi compartment (6). Within the ECD, human and mouse BCMA shares 62% amino acid identity. The expression of BCMA has also been linked to various cancers, autoimmune disorders, and infectious diseases (7). Proteolytic shedding of the BCMA extracellular domain generats soluble BCMA (sBCMA) via direct cleavage by gamma -secretase, and elevated sBCMA levels in serum may correlate with disease activity (8). More recently, BCMA has been indicated as a possible biomarker in various human immunological disease, and as a potential therapeutic target for multiple myeloma (MM) (9-11).
