CC -!- FUNCTION: Component of the srb8-11 complex. The srb8-11 complex is a
CC regulatory module of the Mediator complex which is itself dependent
CC transcription. The srb8-11 complex may be involved in the
CC transcriptional repression of a subset of genes regulated by Mediator.
CC It may inhibit the association of the Mediator complex with RNA
CC polymerase II to form the holoenzyme complex. The srb8-11 complex
CC phosphorylates the C-terminal domain (CTD) of the largest subunit of
CC RNA polymerase II (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
