B cell activating factor (BAFF), a ligand belonging to the tumor necrosis, factor (TNF) family, plays a critical role in regulating survival and, activation of peripheral B cell populations and has been associated with, autoimmune disease. BAFF is known to interact with three receptors, BCMA, TACI and BAFF-R, that have distant similarities with other receptors of, the TNF family. We have determined the crystal structure of the, TNF-homologous domain of BAFF at 2.8 A resolution. The structure reveals, significant differences when compared to other TNF family members, including an unusually long D-E loop that participates in the formation of, a deep, concave and negatively charged region in the putative receptor, binding site. The BAFF structure was further used to generate a homology, model of APRIL, a closely related TNF family ligand that also binds to, BCMA and TACI, but not BAFF-R. Analysis of the putative receptor binding, sites of BAFF and APRIL suggests that differences in the D-E loop, structure and electrostatic surface potentials may be important for, determining binding specificities for BCMA, TACI and BAFF-R.

Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B- and T-cell function and the regulation of humoral immunity. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B-cells and the B-cell response.<ref>PMID:10973284</ref> Isoform 2 seems to inhibit isoform 1 secretion and bioactivity (By similarity).<ref>PMID:10973284</ref>

B cell activating factor (BAFF), a ligand belonging to the tumor necrosis factor (TNF) family, plays a critical role in regulating survival and activation of peripheral B cell populations and has been associated with autoimmune disease. BAFF is known to interact with three receptors, BCMA, TACI and BAFF-R, that have distant similarities with other receptors of the TNF family. We have determined the crystal structure of the TNF-homologous domain of BAFF at 2.8 A resolution. The structure reveals significant differences when compared to other TNF family members, including an unusually long D-E loop that participates in the formation of a deep, concave and negatively charged region in the putative receptor binding site. The BAFF structure was further used to generate a homology model of APRIL, a closely related TNF family ligand that also binds to BCMA and TACI, but not BAFF-R. Analysis of the putative receptor binding sites of BAFF and APRIL suggests that differences in the D-E loop structure and electrostatic surface potentials may be important for determining binding specificities for BCMA, TACI and BAFF-R.
