==Crystal structure of sTALL-1 with BAFF-R==
[[http://www.uniprot.org/uniprot/TR13C_HUMAN TR13C_HUMAN]] Defects in TNFRSF13C are the cause of immunodeficiency common variable type 4 (CVID4) [MIM:[http://omim.org/entry/613494 613494]]; also called antibody deficiency due to BAFFR defect. CVID4 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low.<ref>PMID:19666484</ref>

== Function ==
[https://www.uniprot.org/uniprot/TN13B_HUMAN 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.<ref>PMID:10973284</ref>  Isoform 2 seems to inhibit isoform 1 secretion and bioactivity (By similarity).<ref>PMID:10973284</ref>
