BAFF binds to three TNF receptor superfamily members: B-cell maturation antigen (BCMA TNFRSF17), transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI TNFRSF13B) and BAFF receptor (BAFF R BR3 TNFRSF13C). These receptors are type III transmembrane proteins that lack a signal peptide. Whereas TACI and BCMA bind BAFF and another TNF superfamily ligand, APRIL (a proliferation-inducing ligand), BAFF R selectively binds BAFF.
TNFR2 CD120b TNFR1B Protein, Human, Recombinant (aa 1-268, M196A, His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 27.7 kDa and the accession number is P20333-2.
