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 (By similarity). {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. Interacts with PPARG (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the Mediator complex subunit 20 family.
CC       {ECO:0000305}.
