Recombinant Human Mediator of RNA polymerase II transcription subunit 21 (MED21)

Uniprot Id

Q13503

Target Species

Human

Target Name

MED21

Target Full Name

Mediator of RNA polymerase II transcription subunit 21

Target 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.

Target Subcellular Location

Nucleus.

Target Protein Families

Mediator complex subunit 21 family

Target Synonyms

MED21; SRB7; SURB7; Mediator of RNA polymerase II transcription subunit 21; Mediator complex subunit 21; RNA polymerase II holoenzyme component SRB7; RNAPII complex component SRB7; hSrb7

Target Background

This gene encodes a member of the mediator complex subunit 21 family. The encoded protein interacts with the human RNA polymerase II holoenzyme and is involved in transcriptional regulation of RNA polymerase II transcribed genes. A pseudogene of this gene is located on chromosome 8. Alternative splicing results in multiple transcript variants.
