      Background InformationPyruvate kinase PKLR (UniProt: P12928-2; also known as EC:2.7.1.40, L-PK, Pyruvate kinase isozymes L/R) is encoded by the Pklr gene (Gene ID: 24651) in rat. Pyruvate kinas (PK) is a key glycolytic enzyme that catalyzes the hydrolysis of phosphoenolpyruvate (PEP) to pyruvate, generating ATP in this process. Four tissue specific isozymes of PK have been described in mammals: L (liver), R (erythrocytes), M1 (muscle) and ubiquitous M2. Except for M1 isozyme all other isozymes display positive cooperative kinetic behavior upon binding the allosteric activator fructose-1,6-diphosphate and in the presence of increasing concentrations of PEP. Phosphorylation of PK liver isozyme at serine 113 has been correlated with insulin resistance in rats fed a high-fat diet. Mice fed a high fat diet exhibit a significantly increased level of phospho-Ser 113 form, which declines significantly upon treatment with a pyruvate kinase activator. It has been shown that in rats fed a high-fat diet CDKs are activated and cause phosphorylation of serine 113. The amino acid sequence surrounding pS113 site is shown to have features of a CDK substrate. Phosphorylation of liver PK at serine 113 results in its retention in the nucleus and inhibition of CDK can reduce its nuclear retention and cause an increase in cytosolic enzyme activity.
