RL Plant Cell 27:2880-2893(2015).
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. The Mediator complex, having a compact
CC conformation in its free form, is recruited to promoters by direct
CC interactions with regulatory proteins and serves for the assembly of a
CC functional pre-initiation complex with RNA polymerase II and the
CC general transcription factors.
CC -!- SUBUNIT: Component of the Mediator complex (PubMed:17560376,
CC PubMed:22021418). Interacts with MEE14/CBP1 (PubMed:26462908).
CC {ECO:0000269|PubMed:17560376, ECO:0000269|PubMed:22021418,

CC -!- INTERACTION:
CC Q9LYW3; F4IXJ7: MED6; NbExp=2; IntAct=EBI-1386173, EBI-1386187;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the Mediator complex subunit 7 family.
CC {ECO:0000305}.
