| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Plays a key role in the control of the eukaryotic cell cycle. It is required in higher cells for entry into S-phase and mitosis. p34 is a component of the kinase complex that phosphorylates the repetitive C-terminus of RNA polymerase II. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate. |
| Enzyme regulation | Phosphorylation at Thr-20 or Tyr-21 inactivates the enzyme, while phosphorylation at Thr-162 activates it By similarity. |
| Subunit structure | Forms a stable but non-covalent complex with a regulatory subunit and with a cyclin. |
| Sequence similarities | Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily. Contains 1 protein kinase domain. |
