Also known as PBEF
Summary
NAMPT (nicotinamide phosphoribosyltransferase, HGNC:30092) is a protein-coding gene on chromosome 7q22.3, encoding Nicotinamide phosphoribosyltransferase (P43490). Catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD. It is a selective cancer dependency (DepMap: 33.6% of cell lines).
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.

Literature-anchored findings (GeneRIF, showing 40)

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-BMAL1 heterodimer from NAD-dependent SIRT1-mediated suppression.
Subunit / interactions. Homodimer.
Subcellular location. Nucleus. Cytoplasm. Secreted.
Tissue specificity. Expressed in large amounts in bone marrow, liver tissue, and muscle. Also present in heart, placenta, lung, and kidney tissues.
Activity regulation. Inhibited by FK866. FK866 competes for the same binding site as nicotinamide, but due to its very low dissociation rate, it is essentially an irreversible inhibitor.
Pathway. Cofactor biosynthesis; NAD(+) biosynthesis; nicotinamide D-ribonucleotide from 5-phospho-alpha-D-ribose 1-diphosphate and nicotinamide: step 1/1.
Similarity. Belongs to the NAPRTase family.
