This entry represents a domain found in the human Mediator of RNA polymerase II transcription subunit 14 (Med14) and related proteins. Med14 is a 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 [1]. The major portion of Med14 exists in the Head-Shoulder module of the Mediator and consists of nine tandem repeats (RM1 to RM9), which are arranged in an atypical right-handed helix [2]. This entry represents a domain located at the C terminus and predicted to adopt a globular alpha/beta structure.
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 Me ...
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].
Mediator complex subunit 16, central helical bridge
Med16 is one of the subunits of the Tail portion of the Mediator complex and is required for lipopolysaccharide gene-expression. This entry represents the central helical bridge domain [1,2].
Med16 is one of the subunits of the Tail portion of the Mediator complex and is required for lipopolysaccharide gene-expression [2]. This is the small alpha-beta domain found at the C-terminal of Mediator complex subunit 16 [1].
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 ...
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 RWD domain.
