MEDIATOR COMPLEX -
The Mediator (MED) complex serves as a hub for transcriptional signaling events. MED bridges transcriptional activators and repressors. This large multi-protein complex has a central core conserved from yeast to humans. The core is composed of three modules: head, middle, and tail. A separate module, the Cdk8 kinase module, composed of Cdk8, CycC, kto and skd, serves as a regulator. (Adapted from FBrf0226415 and FBrf0191850).
Protein Function (UniProtKB)
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. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors (By similarity). Required for activated transcription of the MtnA, MtnB and MtnD genes.
