BAFF in B-Cell Signaling

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


BAFF (B-cell activating factor), is a member of the TNF (tumor necrosis factor) ligand family that plays important roles in B-cell homeostasis, tolerance, and malignancy [Ref.1). It is also known as BLyS (B lymphocyte stimulator) protein, TALL-1 (TNF and apoptosis ligand-related leukocyte-expressed ligand-1), zTNF4, CD257, TNFSF13B, TNFS20 (TNF superfamily member) and THANK (TNF homolog that activates apoptosis, NF-B and c-Jun NH2-terminal kinase). It functions through three receptors i.e. TACI, BCMA and BAFFR (BAFF-receptor) (Ref.1).

Interaction of BAFF with BAFFR leads to recruitment of TRAF3 to the receptor and it is subsequently degraded by the combined actions of TRAF2 and cIAP1/2 (Ref.2). Lack of TRAF3 deactivates the TRAF/cIAP complex, releasing NIK and allowing it to accumulate in the cell. NIK then facilitates [...]
