ATP Synthase Protein - 3d rendered image. Medical microbiology concept.  Structure and conformational states of the bovine mitochondrial ATP (Adenosine triphosphate) synthase. Chemical energy is synthesized in eukaryotic cells primarily. Hydrolase. Hologram view. HUD, FUI
PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.
