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 (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q9CQA5-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9CQA5-2; Sequence=VSP_027918, VSP_027919;
CC -!- SIMILARITY: Belongs to the Mediator complex subunit 4 family.
CC {ECO:0000305}.
