== Disease ==
[https://www.uniprot.org/uniprot/MED25_HUMAN MED25_HUMAN] Charcot-Marie-Tooth disease type 2B2. The disease is caused by mutations affecting the gene represented in this entry.<ref>PMID:19290556</ref>
== Function ==
[https://www.uniprot.org/uniprot/MED25_HUMAN MED25_HUMAN] 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 RARA/RXRA-mediated transcription.<ref>PMID:14657022</ref> <ref>PMID:14983011</ref> <ref>PMID:17641689</ref>

== Publication Abstract from PubMed ==
MED25 (ARC92/ACID1) is a 747 residues subunit specific to higher eukaryote Mediator complex, an essential component of the RNA polymerase II general transcriptional machinery. MED25 is a target of the Herpes simplex virus transactivator protein VP16. MED25 interacts with VP16 through a central MED25 PTOV (Prostate tumour overexpressed)/ACID (Activator interacting domain) domain of unknown structure. As a first step towards understanding the mechanism of recruitment of transactivation domains by MED25, we report here the NMR structure of the MED25 ACID domain. The domain architecture consists of a closed beta-barrel with seven strands (Beta1-Beta7) and three alpha-helices (H1-H3), an architecture showing similarities to that of the SPOC (Spen paralog and ortholog C-terminal domain) domain-like superfamily. Preliminary NMR chemical shift mapping showed that VP16 H2 (VP16C) interacts with MED25 ACID through one face of the beta-barrel, defined by strands B4-B7-B6.
