Protein
Cell division control protein 2 homolog 1
Gene
CDC2A
Organism
Medicago sativa (Alfalfa)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

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 activityi

ATP + a protein = ADP + a phosphoprotein.
ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate.

Enzyme regulationi

Phosphorylation at Thr-11 or Tyr-12 inactivates the enzyme, while phosphorylation at Thr-158 activates it By similarity.
