Détails Produit

Product Description: Nicotinamide phosphoribosyltransferase (NAmPRTase or Nampt) also known as pre-B cell colony-enhancing factor 1 (PBEF1) or visfatin is the rate-limiting enzyme in the nicotinamide adenine dinucleotide (NAD+) salvage pathway that converts nicotinamide to nicotinamide mononucleotide in mammals to enable NAD+ biosynthesis. In addition it has been shown to be an adipokine that is localized in the bloodstream and has various functions, including the promotion of vascular smooth muscle cell maturation and inhibition of neutrophil apoptosis. It activates insulin receptor and has insulin-mimetic effects, lowering blood glucose and improving insulin sensitivity. The protein is highly expressed in visceral fat and serum levels of the protein correlate with obesity. The recombinant Nampt (mouse) (rec.) (enzymatically active) (Prod. No. AG-40B-0179) shows activity to convert nicotinamide + phosphoribosyltransferase (PRPP) to nicotinamide mononucleotide (NMN). It migrates as a homodimer on a size exclusion chromatography (SEC) column.
