a pantothenate kinase that catalyzes the first committed step in the biosynthesis of coenzyme A, an essential cofactor in cellular metabolism. PANK4 is ubiquitously expressed but is enriched in muscle. Plays a role in the physiological regulation of the intracellular CoA concentration. Regulated by feedback inhibition by CoA and its thioesters. Interacts with M2-type pyruvate kinase (PKM2) and may modulate glucose metabolism through regulating the activity of PKM2. Expression is up-regulated by high glucose concentrations. Note: This description may include information from UniProtKB.
