MED1/TRAP220 exists predominantly in a TRAP/ Mediator subpopulation enriched in RNA polymerase II and is required for ER-mediated transcription.

Zhang X, Krutchinsky A, Fukuda A, Chen W, Yamamura S, Chait BT, Roeder RG

Human TRAP/Mediator is a key coactivator for many transcription factors that act through direct interactions with distinct subunits, and MED1/TRAP220 is the main subunit target for various nuclear receptors. Remarkably, the current study shows that MED1/TRAP220 only exists in a TRAP/Mediator subpopulation (less then 20% of the total) that is greatly enriched in specific TRAP/Mediator subunits and is tightly associated ...

Affinity Capture-Western
Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
