Protein

Cell division control protein 2 homolog 2

Gene

CDC2B

Organism
Medicago sativa (Alfalfa)
Status
Reviewed - Annotation score: 3 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.

Enzyme regulationi

Phosphorylation at Thr-14 or Tyr-15 inactivates the enzyme, while phosphorylation at Thr-161 activates it.By similarity
