Protein

Cyclin-dependent kinase 12

Gene

cdk12

Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Cyclin-dependent kinase that phosphorylates the C-terminal domain (CTD) of the large subunit of RNA polymerase II (POLR2A), thereby acting as a key regulator of transcription elongation. Regulates the expression of genes involved in DNA repair and is required for the maintenance of genomic stability. Preferentially phosphorylates 'Ser-5' in CTD repeats that are already phosphorylated at 'Ser-7', but can also phosphorylate 'Ser-2'. Required for RNA splicing, possibly by phosphorylating srsf1/sf2 (By similarity).By similarity

Catalytic activityi

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