Annotated 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 RPB1 at serines 2 and 5. The SSN3/SRB10 and
SSN8/SRB11 kinase-cyclin pair may also positively and negatively
regulate numerous transcriptional activators in response to changes in
nutritional and physiological conditions. Phosphorylates GCN4,
promoting its ubiquitin-mediated degradation, and MSN2, promoting its
nuclear exclusion. Phosphorylates STE12, thereby promoting its
degradation and inhibition of filamentous growth. Phosphorylates GAL4,
and this phosphorylation is required for efficient galactose-inducible
transcription. Also phosphorylates BDF1 and the TAF2 subunit of the
TFIID complex.
