Cell 14:685-691(2004). CC -!- FUNCTION: Component of the Mediator complex, a coactivator CC involved in the regulated transcription of nearly all RNA CC polymerase II-dependent genes. Mediator functions as a bridge to CC convey information from gene-specific regulatory proteins to the CC basal RNA polymerase II transcription machinery. Mediator is CC recruited to promoters by direct interactions with regulatory CC proteins and serves as a scaffold for the assembly of a functional CC preinitiation complex with RNA polymerase II and the general CC transcription factors. CC -!- SUBUNIT: Component of the Mediator complex, which is composed of CC MED1, MED4, MED6, MED7, MED8, MED9, MED10, MED11, MED12, MED13, CC MED13L, MED14, MED15, MED16, MED17, MED18, MED19, MED20, MED21, CC MED22, MED23, MED24, MED25, MED26, MED27, MED29, MED30, MED31, CC CCNC, CDK8 and CDC2L6/CDK11. The MED12, MED13, CCNC and CDK8 CC subunits form a distinct module termed the CDK8 module. Mediator CC containing the CDK8 module is less active than Mediator lacking CC this module in supporting transcriptional activation. Individual CC preparations of the Mediator complex lacking one or more distinct CC subunits have been variously termed ARC, CRSP, DRIP, PC2, SMCC and CC TRAP. CC -!- SUBCELLULAR LOCATION: Nucleus (Probable). CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; CC IsoId=A0JLT2-1; Sequence=Displayed; CC Name=2; CC IsoId=A0JLT2-2; Sequence=VSP_028121, VSP_028122; CC Note=No experimental confirmation available; CC -!- SIMILARITY: Belongs to the Mediator complex subunit 19 family.
