Tumor necrosis factor

Gene

TNF

Organism
Tursiops truncatus (Atlantic bottle-nosed dolphin) (Delphinus truncatus)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation (By similarity).By similarity
The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.By similarity

Post-translational modificationi

The soluble form derives from the membrane form by proteolytic processing. The membrane-bound form is further proteolytically processed by SPPL2A or SPPL2B through regulated intramembrane proteolysis producing TNF intracellular domains (ICD1 and ICD2) released in the cytosol and TNF C-domain 1 and C-domain 2 secreted into the extracellular space (By similarity).By similarity
The membrane form, but not the soluble form, is phosphorylated on serine residues. Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1 (By similarity).By similarity
O-glycosylated; glycans contain galactose, N-acetylgalactosamine and N-acetylneuraminic acid.By similarity
