Protein

Cyclin-dependent kinase 12

Gene

cdk-12

Organism
Caenorhabditis elegans
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Cyclin-dependent kinase which displays CTD kinase activity: hyperphosphorylates 'Ser-2' in the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit, thereby acting as a key regulator of transcription elongation. Required for normal reproduction.1 Publication

Catalytic activityi

ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate.1 Publication
ATP + a protein = ADP + a phosphoprotein.
