B-CELL MATURATION ANTIGEN HUMAN

General description

B-cell maturation antigen (BCMA) or tumor necrosis factor receptor superfamily member 17(TNFRSF17), a member of the tumor necrosis factor (TNF) receptor superfamily, binds to B-cell–activating factor (BAFF) and a proliferation-inducing ligand (APRIL). BCMA is expressed on mature B-cells and other B-cell lines. The human BCMA gene codes for a 184 amino acid type I transmembrane protein, which contains a 54 amino acid extracellular domain, a 23 amino acid transmembrane domain, and a 107 amino acid cytoplasmic domain. Recombinant soluble human BCMA is a 50 amino acid polypeptide (5.3kDa) comprising the TNFR homologous region of the BCMA protein.

Biochem/physiol Actions

B-cell maturation antigen (BCMA) or tumor necrosis factor receptor superfamily member 17 (TNFRSF17) plays an important role in B cell development, function and regulation. BCMA also has the capability to activate nuclear factor-κB (NF-κB), janus kinase (JNK) and mitogen activated protein kinases (MAPKs). The protein is expressed in certain cancers like glioblastoma, chronic lymphocytic leukemia, Hodgkin lymphoma and multiple myeloma. It has a role in the maintenance of survival of long-lived plasma cells in bone marrow.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C
