Background
PKM (Pyruvate kinase M) represents alternatively spliced isoforms of pyruvate kinase M family catalyzing final glycolytic step and governing cancer metabolic reprogramming. Alternative splicing yields PKM1 and PKM2. Tetrameric PKM1 exhibits high catalytic activity and drives glycolysis in differentiated normal tissues. PKM2 toggles between tetramer and dimer conformations; low-activity dimeric PKM2 accumulates in tumor cells and underpins Warburg effect. Beyond glycolytic catalysis, nuclear-translocated PKM2 acts as transcriptional co-regulator for proliferative genes. Tumors undergo isoform-switch toward PKM2 to sustain rapid growth.
