Background of the antigen
PANK4 belongs to the pantothenate kinase family. Pantothenate kinase is a key regulatory enzyme in the physiological regulation of the intracellular coenzyme A (CoA) concentration. It catalyzes the first committed step in the universal biosynthetic pathway leading to CoA and is itself subject to regulation through feedback inhibition by CoA. This family member is most abundant in muscle but is expressed in all tissues.
