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 (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the Mediator complex. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Mediator complex subunit 21 family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAS50317.1; Type=Erroneous initiation; Evidence={ECO:0000305};
