CC -!- FUNCTION: Component of the SRB8-11 complex. The SRB8-11 complex is CC a regulatory module of the Mediator complex which is itself CC involved in regulation of basal and activated RNA polymerase II- CC dependent transcription. The SRB8-11 complex may be involved in CC the transcriptional repression of a subset of genes regulated by CC Mediator. It may inhibit the association of the Mediator complex CC with RNA polymerase II to form the holoenzyme complex. The SRB8-11 CC complex phosphorylates the C-terminal domain (CTD) of the largest CC subunit of RNA polymerase II (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. CC -!- CATALYTIC ACTIVITY: ATP + [DNA-directed RNA polymerase] = ADP + CC [DNA-directed RNA polymerase] phosphate. CC -!- COFACTOR: Magnesium (By similarity). CC -!- SUBUNIT: Component of the SRB8-11 complex, a regulatory module of CC the Mediator complex (By similarity). CC -!- SUBCELLULAR LOCATION: Nucleus (Probable). CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC CC Ser/Thr protein kinase family. CDC2/CDKX subfamily. CC -!- SIMILARITY: Contains 1 protein kinase domain.
