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. Required for activated
CC transcription of the MtnA, MtnB and MtnD genes.
CC {ECO:0000269|PubMed:11259581, ECO:0000269|PubMed:16751183}.
CC -!- SUBUNIT: Component of the Mediator complex, which includes at least
CC MED4, MED6, MED14, MED17, MED18, MED20, MED21, MED23, MED24, MED27,
CC MED30 and MED31. Interacts with MED10 and MED21.
CC {ECO:0000269|PubMed:11259581, ECO:0000269|PubMed:12021283,
CC ECO:0000269|PubMed:15477388}.
CC -!- INTERACTION:
CC Q9VS38; A1ZB42: MED9; NbExp=3; IntAct=EBI-187169, EBI-194372;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- DEVELOPMENTAL STAGE: Maternally encoded. Expression decreases during
CC larval stages then rises during mid-pupal metamorphosis.
CC {ECO:0000269|PubMed:11259581}.
CC -!- SIMILARITY: Belongs to the Mediator complex subunit 4 family.
CC {ECO:0000305}.
