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. May be part of a complex containing NF2/merlin that participates in cellular signaling to the actin cytoskeleton downstream of tyrosine kinase signaling pathways. {ECO:0000269PubMed:15467741}.
Subcellular Localization Nucleus {ECO:0000269PubMed:15467741}. Cytoplasm {ECO:0000269PubMed:15467741}. Membrane {ECO:0000269PubMed:15467741}; Peripheral membrane protein {ECO:0000269PubMed:15467741}. Note=According to PubMed:15467741, it is cytoplasmic and mainly membrane-associated.
