Target

  • 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.
  • Tissue specificity

    Expressed in large amounts in bone marrow, liver tissue, and muscle. Also present in heart, placenta, lung, and kidney tissues.
  • Pathway

    Cofactor biosynthesis; NAD(+) biosynthesis; nicotinamide D-ribonucleotide from 5-phospho-alpha-D-ribose 1-diphosphate and nicotinamide: step 1/1.
  • Sequence similarities

    Belongs to the NAPRTase family.
  • Cellular localization

    Cytoplasm.

    The molecular weight observed is consistent with what has been described in the literature (PMID:25368373, PMID:12782293).

  • Immunohistochemical analysis of paraffin-embedded human bladder cancer tissue labeling Visfatin with ab236873 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) Ready to use. Nuclear and cytoplasmic staining in human bladder cancer (PMID:26396920) is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) Ready to use.
