Gene Summary
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. (UniProt, Q9VP05)

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).

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
