Function

[TN13B_HUMAN] Cytokine that binds to TNFRSF13B/TACI and TNFRSF17/BCMA. TNFSF13/APRIL binds to the same 2 receptors. 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.^[1] Isoform 2 seems to inhibit isoform 1 secretion and bioactivity (By similarity).^[2]

Publication Abstract from PubMed

TALL-1/BAFF/BLyS was recently identified as a member of the tumor necrosis factor (TNF) ligand family. The crystal structure of the functional soluble TALL-1 (sTALL-1) has been determined at 3.0 A. sTALL-1 forms a virus-like assembly with 200 A diameter in the crystals, containing 60 sTALL-1 monomers. The cluster formation is mediated by a "flap" region of the sTALL-1 monomer. The virus-like assembly was also detected in solution using gel filtration and electron microscopy. Deletion of the flap region disrupted the formation of the virus-like assembly. The mutant sTALL-1 still bound its receptor but could not activate NF-kappaB and did not stimulate B lymphocyte proliferation. Finally, we found the virus-like cluster of sTALL-1 exists in physiological condition. We propose that this virus-like assembly of sTALL-1 is the functional unit for TALL-1 in vivo.

Crystal structure of sTALL-1 reveals a virus-like assembly of TNF family ligands.,Liu Y, Xu L, Opalka N, Kappler J, Shu HB, Zhang G Cell. 2002 Feb 8;108(3):383-94. PMID:11853672^[3]
