Product Detail	This gene encodes a protein that catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, one step in the biosynthesis of nicotinamide adenine dinucleotide. The protein belongs to the nicotinic acid phosphoribosyltransferase (NAPRTase) family and is thought to be involved in many important biological processes, including metabolism, stress response and aging. This gene has a pseudogene on chromosome 10. [provided by RefSeq, Feb 2011]. 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. Subunit: Homodimer. Subcellular Location: Cytoplasm. Nucleus. Tissue Specificity: Expressed in large amounts in bone marrow, liver tissue, and muscle. Also present in heart, placenta, lung, and kidney tissues. Similarity: Belongs to the NAPRTase family.

Visfatin的表达受炎症反应因子和多种激素的调节.PBEF-1可能是联系机体糖脂代谢的重要分子,它的发现可为揭示Diabetes与肥胖的发生发展机制提供新的研究思路,为代谢综合征的治疗提供新方案.
