Biol. Chem. 280:18171-18178(2005). 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. The Mediator CC complex, having a compact conformation in its free form, is CC recruited to promoters by direct interactions with regulatory CC proteins and serves for the assembly of a functional preinitiation CC complex with RNA polymerase II and the general transcription CC factors. The Mediator complex unfolds to an extended conformation CC and partially surrounds RNA polymerase II, specifically CC interacting with the unphosphorylated form of the C-terminal CC domain (CTD) of RNA polymerase II. The Mediator complex CC dissociates from the RNA polymerase II holoenzyme and stays at the CC promoter when transcriptional elongation begins. CC {ECO:0000269|PubMed:11555651, ECO:0000269|PubMed:16076843, CC ECO:0000269|PubMed:16263706}. CC -!- SUBUNIT: Component of the Mediator complex, which is composed of CC at least 21 subunits that form three structurally distinct CC submodules. The Mediator head module contains MED6, MED8, MED11, CC SRB4/MED17, SRB5/MED18, ROX3/MED19, SRB2/MED20 and SRB6/MED22, the CC middle module contains MED1, MED4, NUT1/MED5, MED7, CSE2/MED9, CC NUT2/MED10, SRB7/MED21 and SOH1/MED31, and the tail module CC contains MED2, PGD1/MED3, RGR1/MED14, GAL11/MED15 and SIN4/MED16. CC The head and the middle modules interact directly with RNA CC polymerase II, whereas the elongated tail module interacts with CC gene-specific regulatory proteins. MED7 interacts directly with CC MED1, MED4 and SRB7/MED21. {ECO:0000269|PubMed:11555651, CC ECO:0000269|PubMed:15710619, ECO:0000269|PubMed:17192271}.

CC -!- MISCELLANEOUS: Present with 7598 molecules/cell in log phase SD CC medium. {ECO:0000269|PubMed:14562106}. CC -!- SIMILARITY: Belongs to the Mediator complex subunit 7 family. CC {ECO:0000305}.
