Mediator complexes are basic necessities for linking transcriptional regulators to RNA polymerase II. This domain, Med1, is conserved from plants to fungi to humans and forms part of the Med9 submodule of the Srb/Med complex. it is one of three subunits essential for viability of the whole organism via its role in environmentally-directed cell-fate decisions [1]. Med1 is part of the tail region of the Mediator complex [2].
This domain is found at the C-terminus of the Med15 subunit of the ARC-Mediator co-activator. In addition, Med15 is a critical transducer of gene activation signals that control early metazoan development. This domain is structurally similar to the R ...

Med18 is one subunit of Mediator, a head-module multiprotein complex, that stimulates basal RNA polymerase II (Pol II) transcription. Med18 consists of an eight-stranded beta-barrel with a central pore and three flanking helices. It complexes with Med8 and Med20 proteins by forming a heterodimer of two-fold symmetry with Med20 and binding the C-terminal alpha-helix region of Med8 across the top of its barrel. This complex creates a multipartite TBP-binding site that can be modulated by transcriptional activators [1].
