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].
