Recombinant Human MED11 Protein Fragment (residues 2-117) is a high-quality, soluble protein designed for structural and functional studies. This fragment of Mediator of RNA polymerase II transcription subunit 11 represents a stable, biochemically tractable unit ideal for investigating the Mediator complex's role in transcriptional regulation.

Mediator of RNA polymerase II transcription subunit 11 (MED11) is an essential component of the Mediator complex, a critical coactivator that regulates transcription of nearly all RNA polymerase II-dependent genes. The Mediator complex functions as a molecular bridge, conveying regulatory information from gene-specific transcription factors to the basal RNA polymerase II machinery. By facilitating the assembly of functional pre-initiation complexes at gene promoters, MED11 contributes to precise transcriptional control mechanisms fundamental to cellular processes. This nuclear-localized protein plays a vital role in connecting regulatory signals with the core transcriptional apparatus, making it a key target for understanding gene expression regulation in human cells.
