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.
Organic objects form a triangle. Artificial space incorporating organic materials.\nThis work was policy within one month. It is also an original work for this brief and cannot be used elsewhere.
