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 preinitiation complex with RNA polymerase II and the general
CC transcription factors (By similarity). May play a role in transcription
CC elongation (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the Mediator complex. {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the Mediator complex subunit 26 family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL25557.1; Type=Frameshift; Evidence={ECO:0000305};
CC Sequence=BAB09406.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
