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. p34 is a component of the kinase complex that phosphorylates the repetitive C-terminus of RNA polymerase II By similarity. UniProtKB P06493

Catalytic activity

ATP + a protein = ADP + a phosphoprotein. UniProtKB P06493

ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate. UniProtKB P06493

Enzyme regulation

Phosphorylation both activates and inactivates the enzyme depending on the site of phosphorylation By similarity. UniProtKB P34556

Subunit structure

Forms a stable but non-covalent complex with a regulatory subunit and with a cyclin. Interacts with cks-1 By similarity. UniProtKB P06493 UniProtKB P34556

Subcellular location

Nucleus By similarity. Cytoplasm › cytoskeleton › centrosome By similarity UniProtKB P39951.

Sequence similarities

Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.

Contains 1 protein kinase domain.
