Proteome Res. 12:260-271(2013). CC -!- FUNCTION: Component of the Mediator complex, a coactivator involved in CC the regulated 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. 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. CC {ECO:0000269|PubMed:15175163}.
