生物信息

基因名称 TNFSF13B
全名 tumor necrosis factor (ligand) superfamily, member 13b
背景介绍 The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFFR. This cytokine is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells. Alternatively spliced transcript variants encoding distinct isoforms have been identified.

生物功能 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.

Isoform 2 seems to inhibit isoform 1 secretion and bioactivity.

Isoform 3: Acts as a transcription factor for its own parent gene, in association with NF-kappa-B p50 subunit, at least in autoimmune and proliferative B-cell diseases. The presence of Delta4BAFF is essential for soluble BAFF release by IFNG/IFN-gamma-stimulated monocytes and for B-cell survival. It can directly or indirectly regulate the differential expression of a large number of genes involved in the innate immune response and the regulation of apoptosis. [UniProt]
细胞定位 Cell membrane; Single-pass type II membrane protein. Tumor necrosis factor ligand superfamily member 13b, soluble form: Secreted. [UniProt]
翻译后修饰 The soluble form derives from the membrane form by proteolytic processing.

Isoform 2 is not efficiently shed from the membrane unlike isoform 1.

N-glycosylated. [UniProt]
