| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Glycolytic enzyme that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate (PEP) to ADP, generating ATP. Stimulates POU5F1-mediated transcriptional activation By similarity. |
| Catalytic activity | ATP + pyruvate = ADP + phosphoenolpyruvate. |
| Cofactor | Magnesium. Potassium. |
| Enzyme regulation | Isoform M2 is allosterically activated by D-fructose 1,6-biphosphate (FBP). Inhibited by oxalate and 3,3',5-triiodo-L-thyronine (T3) By similarity. |
| Pathway | Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 5/5. |
| Subunit structure | Monomer and homotetramer. Exists as a monomer in the absence of fructose 1,6 bi-phosphate (FBP), and reversibly associates to form a homotetramer in the presence of FBP. The monomeric form binds T3. Tetramer formation induces pyruvate kinase activity. Interacts with HERC1, POU5F1 and PML By similarity. |
| Subcellular location | |
| Tissue specificity | Embryonic stem cells and embryonal carcinoma cells. Ref.7 |
| Post-translational modification | Phosphorylated upon DNA damage, probably by ATM or ATR By similarity. |
| Miscellaneous | There are 4 isozymes of pyruvate kinase in mammals: L, R, M1 and M2. L type is major isozyme in the liver, R is found in red cells, M1 is the main form in muscle, heart and brain, and M2 is found in early fetal tissues. |
| Sequence similarities | Belongs to the pyruvate kinase family. |
