Protein attributes

Sequence length	323 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	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 By similarity.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein. ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate.
Enzyme regulation	Phosphorylation at Thr-14 or Tyr-15 inactivates the enzyme, while phosphorylation at Thr-180 activates it By similarity.
Subunit structure	Forms a stable but non-covalent complex with a regulatory subunit (SUC1) and with a cyclin.
Sequence similarities	Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily. Contains 1 protein kinase domain.
