General annotation (Comments)

Function

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 activity

ATP + a protein = ADP + a phosphoprotein.

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

Cofactor

Magnesium By similarity.

Subunit structure

Component of the srb8-11 complex, a regulatory module of the Mediator complex By similarity.

Subcellular location

Nucleus Probable.

Sequence similarities

Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.

Contains 1 protein kinase domain.

Sequence caution

The sequence BAE60857.1 differs from that shown. Reason: Erroneous gene model prediction.
