Protein Structure
UniProt Annotation
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. {ECO:0000269PubMed:10406464, ECO:0000269PubMed:11867769, ECO:0000269PubMed:12037571, ECO:0000269PubMed:12218053, ECO:0000269PubMed:12556447, ECO:0000269PubMed:14636573, ECO:0000269PubMed:15340084, ECO:0000269PubMed:15471764, ECO:0000269PubMed:15989967, ECO:0000269PubMed:16574658, ECO:0000269PubMed:9653119}.
