Protein

Cyclin-dependent kinase 2

Gene

cdk2

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in the control of the cell cycle. Interacts with cyclins A, B, D, or E. Activity of CDK2 is maximal during S phase and G2.1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulationi

Phosphorylation at Thr-14 or Tyr-15 inactivates the enzyme, while phosphorylation at Thr-160 activates it (By similarity). Activated by spdya.By similarity1 Publication
