Function Required for transcriptional activation subsequent to the assembly of the preinitiation complex (By similarity). 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 transcriptional activation by adenovirus E1A protein. Required for ELK1-dependent transcriptional activation in response to activated Ras signaling. {ECO:0000250, ECO:0000269PubMed:10353252, ECO:0000269PubMed:14759369, ECO:0000269PubMed:16595664}.
Subcellular Localization Nucleus {ECO:0000305}.
Disease Associations Mental retardation, autosomal recessive 18 (MRT18) [MIM:614249]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. {ECO:0000269PubMed:21868677}. Note=The disease is caused by mutations affecting the gene represented in this entry.
