Function
| Annotated function |
Component of the Mediator complex, a coactivator involved in
the regulated transcription of nearly all RNA polymerase II-dependent
genes. Mediator functions as a bridge to convey information from gene-
specific regulatory proteins to the basal RNA polymerase II
transcription machinery. The Mediator complex, having a compact
conformation in its free form, is recruited to promoters by direct
interactions with regulatory proteins and serves for the assembly of a
functional preinitiation complex with RNA polymerase II and the general
transcription factors. The Mediator complex unfolds to an extended
conformation and partially surrounds RNA polymerase II, specifically
interacting with the unphosphorylated form of the C-terminal domain
(CTD) of RNA polymerase II. The Mediator complex dissociates from the
RNA polymerase II holoenzyme and stays at the promoter when
transcriptional elongation begins.
