Nicotinamide riboside kinase 2

Nicotinamide riboside kinase 2 is an enzyme that in humans is encoded by the NMRK2 gene (previously ITGB1BP3). As a nicotinamide riboside kinase (), this enzyme functions to phosphorylate nicotinamide riboside which produces nicotinamide mononucleotide, an important enzyme cofactor. Nicotinamide riboside kinase 2 is primarily found in the muscle and heart, unlike the other known human isoform, nicotinamide riboside kinase 1, which is more widely expressed.

Interactions NMRK2 has been shown to interact with ST7.
