Comments

FUNCTION: Plays a key role in the control of the eukaryotic cell cycle. Component of the kinase complex that phosphorylates the repetitive C-terminus of RNA polymerase II.
CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein.
CATALYTIC ACTIVITY: ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate.
ENZYME REGULATION: Phosphorylation at Thr-11 or Tyr-12 inactivates the enzyme, while phosphorylation at Thr-158 activates it (By similarity).
TISSUE SPECIFICITY: Found in most organs including root, young leaf, stem, vegetative meristem and flower bud.
SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.
SIMILARITY: Contains 1 protein kinase domain.
