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. {ECO:0000256|ARBA:ARBA00025687,
CC ECO:0000256|RuleBase:RU364141}.
CC -!- SUBUNIT: Component of the Mediator complex.
CC {ECO:0000256|RuleBase:RU364141}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123,
CC ECO:0000256|RuleBase:RU364141}.
CC -!- SIMILARITY: Belongs to the Mediator complex subunit 4 family.
CC {ECO:0000256|ARBA:ARBA00009626, ECO:0000256|RuleBase:RU364141}.
