Intracellular human Nampt (visfatin/PBEF) (amino acids 1-491) is fused at the C-terminus to a His-tag. Shows adipogenic effects in stimulated differentiating 3T3-L1 cells. Lyophilized. Salt-free. Nicotinamide phosphoribosyltransferase (Nampt, pre-B cell colony-enhancing factor, PBEF, Visfatin) is an 52kDa adipokine...

Protein function: Catalyzes the condensation of nicotinamide with 5- phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD. It is the rate limiting component in the mammalian NAD biosynthesis pathway. The secreted form behaves both as a cytokine with...
