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 immunomodulating properties and an adipokine with anti-diabetic properties, it has no enzymatic activity, partly because of lack of activation by ATP, which has a low level in extracellular space and plasma. Plays a role in the modulation of circadian clock function. NAMPT-dependent oscillatory production of NAD regulates oscillation of clock target gene expression by releasing the core clock component: CLOCK-ARNTL/BMAL1 heterodimer from NAD-dependent SIRT1-mediated suppression. {ECO:0000250|UniProtKB:P43490, ECO:0000250|UniProtKB:Q99KQ4}. |
Subcellular Location | Nucleus {ECO:0000269|PubMed:12782293}. Cytoplasm {ECO:0000269|PubMed:12782293}. Secreted {ECO:0000250|UniProtKB:P43490}. Note=Under non-inflammatory conditions, visfatin predominantly exhibits a granular pattern within the nucleus. Secreted by endothelial cells upon IL-1beta stimulation. Abundantly secreted in milk, reaching 100-fold higher concentrations compared to maternal serum. {ECO:0000250|UniProtKB:P43490}. |
Tissue Specificity | Expressed in various tissues. At the highest level in liver and at the second highest in heart. The amount is higher in heart than in lung. {ECO:0000269|PubMed:12782293}. |
