B-cell maturation antigen (BCMA or BCM), also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF17), is a protein that in humans is encoded by the TNFRSF17 gene.

TNFRSF17 is a cell surface receptor of the TNF receptor superfamily which recognizes B-cell activating factor (BAFF).[1][2][3]

Function[edit | edit source]

The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is preferentially expressed in mature B lymphocytes, and may be important for B cell development and autoimmune response. This receptor has been shown to specifically bind to the tumor necrosis factor (ligand) superfamily, member 13b (TNFSF13B/TALL-1/BAFF), and to lead to NF-kappaB and MAPK8/JNK activation. This receptor also binds to various TRAF family members, and thus may transduce signals for cell survival and proliferation.[3]

Interactions[edit | edit source]

TNFRSF17 has been shown to interact with the B-cell activating factor TNFSF13B.[4][5] A conserved domain at the N-terminus, BCMA TALL-1 binding domain, is required for binding to the TNFSF13B.[4]

Clinical significance - Related Diseases[edit | edit source]

TNFRSF17 is implicated in leukemia, lymphomas, and multiple myeloma [6] (see the "Mitelman Database" [7] and the Atlas of Genetics and Cytogenetics in Oncology and Haematology,[8]).

As a drug target[edit | edit source]

In 2017, a phase 1 clinical trial employed a CAR-T therapy that targeted BCMA02 in multiple myeloma.[9] Side-effects seen include cytokine release syndrome and mild neurotoxicity.[10]

An antibody-drug conjugate GSK2857916 is in early clinical trials.[11][12] Side effects are expected to include corneal toxicity.[12]
