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.

The RAX/PACT-PKR stress response pathway promotes p53 sumoylation and activation, leading to Gâ‚ arrest.
Cellular stresses, including growth factor deprivation, inflammatory cytokines or viral infection promote RAX/PACT-dependent activation of the double-stranded RNA-dependent protein kinase, PKR, to phosphorylate eIF2α, resulting in translation inhibition and apoptosis. In addition, PKR has been reported to regulate p53, STAT1 and NFκB. Here, we report that RAX/PACT interacts with the SUMO E2 ligase Ubc9 to stimulate p53-Ubc9 association and reversible ... [more]
