Protein

Cell division control protein 2 homolog

Gene
CRK2
Organism
Plasmodium knowlesi (strain H)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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. Component of the kinase complex that phosphorylates the repetitive C-terminus of RNA polymerase II By similarity.

Catalytic activityi

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

Enzyme regulationi

Phosphorylation at Thr-14 or Tyr-15 inactivates the enzyme, while phosphorylation at Thr-158 activates it By similarity.
