Protein: Mediator of RNA polymerase II transcription subunit 20 (Mediator complex subunit 20) (Protein trf-proximal) (dMED20) (dTrap26) (dTrfp) (P91641)
Organism: Drosophila melanogaster (Fruit fly)
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. 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. Required for activated transcription of the MtnA gene.
