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.

Role of steroid receptor coactivators in glucocorticoid and transforming growth factor beta regulation of plasminogen activator inhibitor gene expression.

Li G, Heaton JH, Gelehrter TD

TGFbeta is a major regulator of extracellular matrix deposition and a potent inducer of type-1 plasminogen activator inhibitor (PAI-1) gene expression. We have reported that liganded glucocorticoid receptor (GR) represses TGFbeta transactivation of PAI-1 in Hep3B human hepatoma cells and that it interacts functionally and physically with the C-terminal activation domain of Smad3, a mediator of TGFbeta signaling. The ligand ... [more]
