TNF-alpha protein (His tag), recombinant rabbit

Activity: Testing in progress Protein Construction: A DNA sequence encoding the Rabbit TNF-alpha protein (P04924) (Leu 80-Leu 235) was expressed with a N-His tag. Sequence: Leu 80-Leu 235. Fusion tag: N-His Endotoxin: Please contact us for more information. Apparent Molecular Mass: 18 kDa. Protein function: Tumor necrosis factor alpha (TNFalpha) is the prototypic ligand of the TNF superfamily. TNFalpha forms a homotrimer and functions by activating two types of receptors TNF-R1 (TNF receptor type 1,p55R) and TNF-R2 (TNF receptor type 2,p75R). TNFalpha is a pleiotropic c Protein function: 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. Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance. Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6. [The UniProt Consortium]
