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. The Mediator complex, having a compact conformation in its free form, is recruited to promoters by direct interactions with regulatory proteins and serves for the assembly of a functional pre-initiation complex with RNA polymerase II and the general transcription factors. Component of the Mediator complex (PubMed:17560376, PubMed:22021418). Interacts with MEE14/CBP1 (PubMed:26462908). Belongs to the Mediator complex subunit 7 family.
