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 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Component of the Mediator complex, which is composed of MED1,
CC       MED4, MED6, MED7, MED8, MED9, MED10, MED11, MED12, MED13, MED13L,
CC       MED14, MED15, MED16, MED17, MED18, MED19, MED20, MED21, MED22, MED23,
CC       MED24, MED25, MED26, MED27, MED29, MED30, MED31, CCNC, CDK8 and
CC       CDC2L6/CDK11. The MED12, MED13, CCNC and CDK8 subunits form a distinct
CC       module termed the CDK8 module. Mediator containing the CDK8 module is
CC       less active than Mediator lacking this module in supporting
CC       transcriptional activation. Individual preparations of the Mediator
CC       complex lacking one or more distinct subunits have been variously
CC       termed ARC, CRSP, DRIP, PC2, SMCC and TRAP. The cylin/CDK pair formed
CC       by CCNC/CDK8 also associates with the large subunit of RNA polymerase
CC       II (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the cyclin family. Cyclin C subfamily.
CC       {ECO:0000305}.
