RP IDENTIFICATION.
RG Ensembl;
RL Submitted (NOV-2023) to UniProtKB.
CC -!- FUNCTION: Component of the Mediator complex, a coactivator involved in
CC regulated gene transcription of nearly all RNA polymerase II-dependent
CC genes. Mediator functions as a bridge to convey information from gene-
CC specific regulatory proteins to the basal RNA polymerase II
CC transcription machinery. Mediator is recruited to promoters by direct
CC interactions with regulatory proteins and serves as a scaffold for the
CC assembly of a functional preinitiation complex with RNA polymerase II
CC and the general transcription factors. Binds to and activates cyclin-
CC dependent kinase CDK8 that phosphorylates the CTD (C-terminal domain)
CC of the large subunit of RNA polymerase II (RNAp II), which may inhibit
CC the formation of a transcription initiation complex.
CC {ECO:0000256|ARBA:ARBA00025028}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123}.
CC -!- SIMILARITY: Belongs to the cyclin family. Cyclin C subfamily.
CC {ECO:0000256|ARBA:ARBA00008638}.
