Functioni

Component of the SRB8-11 complex. The SRB8-11 complex is a regulatory module of the Mediator complex which is itself involved in regulation of basal and activated RNA polymerase II-dependent transcription. The SRB8-11 complex may be involved in the transcriptional repression of a subset of genes regulated by Mediator. It may inhibit the association of the Mediator complex with RNA polymerase II to form the holoenzyme complex. The SRB8-11 complex phosphorylates the C-terminal domain (CTD) of the largest subunit of RNA polymerase II By similarity.

Catalytic activityi

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

Cofactori

Magnesium By similarity.
