Abstract

Background: The protein-serine/threonine kinase PIM2 regulates glycolysis, but the mechanism is not fully elucidated. Results: PIM2 interacts with PKM2 and phosphorylates PKM2 on the Thr-454 residue. Conclusion: This phosphorylation of PKM2 increases glycolysis and proliferation in cancer cells. Significance: PIM2-dependent phosphorylation of PKM2 is critical for regulating the Warburg effect in cancer, highlighting PIM2 as a potential therapeutic target.
