Protein

Cell division control protein 2 homolog B

Gene

CDC2B

Organism
Antirrhinum majus (Garden snapdragon)
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.

Catalytic activityi

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

Enzyme regulationi

Phosphorylation at Tyr-2 inactivates the enzyme, while phosphorylation at Thr-148 activates it.By similarity
