背景介绍 B-Cell Maturation Antigen (BCMA), also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF17) or CD269, is a type I membrane protein encoded by the TNFRSF17 gene. TNFRSF17 is a cell surface receptor of the TNF receptor superfamily, that recognizes its ligands including BAFF (B-cell activating factor) and APRIL (a proliferation inducing ligand). BCMA is preferentially expressed in mature B lymphocytes and also on Multiple Myeloma (MM) cells. In vitro, the activation of BCMA by its ligand promotes the differentiation and proliferation of B cells. A vast array of intracellular activity is involved in BCMA-induced signal transduction, including activation of the NF-κB signaling pathway. The bioactivity of BAFF and APRIL as soluble homotrimers distinguishes them from other TNFSF ligands such as TRAIL, FasL, and CD40L, which are only active as membrane-bound molecules. 产品介绍 The BCMA / NF-κB - HEK293 recombinant cell line has been transfected with full-length human BCMA cDNA (Genbank #NM_001192) under control of a CMV promoter for high constitutive expression. The NF-κB-luciferase reporter is also stably integrated into the genome. The firefly luciferase gene is controlled by four copies of the NF-κB Response Element upstream of a minimal promoter. Upon ligand binding, active BCMA will initiate the NF-κB signaling pathway, leading to expression of the NF-κB-controlled luciferase reporter.
