 -!- FUNCTION: Component of the Mediator complex, a coactivator
     involved in the regulated 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

 -!- SUBUNIT: Component of the Mediator complex, which is composed of
     MED1, MED4, MED6, MED7, MED8, MED9, MED10, MED11, MED12, MED13,
     MED13L, MED14, MED15, MED16, MED17, MED18, MED19, MED20, MED21,
     MED22, MED23, MED24, MED25, MED26, MED27, MED29, MED30, MED31,
     CCNC, CDK8 and CDC2L6/CDK11. The MED12, MED13, CCNC and CDK8
     subunits form a distinct module termed the CDK8 module. Mediator
     containing the CDK8 module is less active than Mediator lacking
     this module in supporting transcriptional activation. Individual
     preparations of the Mediator complex lacking one or more distinct
     subunits have been variously termed ARC, CRSP, DRIP, PC2, SMCC and
     TRAP. This subunit specifically interacts with a number of nuclear
     receptors in a ligand-dependent fashion including AR, ESR1, ESR2,
     PPARA, PPARG, RORA, RXRA, RXRG, THRA, THRB and VDR. Interacts with
     CTNNB1, GABPA, GLI3, PPARGC1A and TP53. Interacts with YWHAH.
     Interacts with CLOCK; this interaction requires the presence of
     THRAP3 (By similarity). Interacts with GATA1 and CCAR1. Interacts
     with NR4A3 (By similarity). {ECO:0000250|UniProtKB:Q925J9,
