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.

STAGA recruits Mediator to the MYC oncoprotein to stimulate transcription and cell proliferation.

Liu X, Vorontchikhina M, Wang YL, Faiola F, Martinez E

Activation of eukaryotic gene transcription involves the recruitment by DNA-binding activators of multiprotein histone acetyltransferase (HAT) and Mediator complexes. How these coactivator complexes functionally cooperate and the roles of the different subunits/modules remain unclear. Here we report physical interactions between the human HAT complex STAGA (SPT3-TAF9-GCN5-acetylase) and a "core" form of the Mediator complex during transcription activation by the MYC ... [more]
