Protein
Cyclin-dependent kinase 8
Gene
Cdk8, AAEL002395
Organism
Aedes aegypti (Yellowfever mosquito) (Culex aegypti)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Component of the Mediator complex, a coactivator involved in regulated gene transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. Phosphorylates the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAp II), which may inhibit the formation of a transcription initiation complex 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.
