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.

WDR5 is essential for assembly of the VISA-associated signaling complex and virus-triggered IRF3 and NF-kappaB activation.

Wang YY, Liu LJ, Zhong B, Liu TT, Li Y, Yang Y, Ran Y, Li S, Tien P, Shu HB

Viral infection causes activation of the transcription factors NF-kappaB and IRF3, which collaborate to induce type I interferons (IFNs) and cellular antiviral response. The mitochondrial outer membrane protein VISA acts as a critical adapter for assembling a virus-induced complex that signals NF-kappaB and IRF3 activation. Using a biochemical purification approach, we identified the WD repeat protein WDR5 as a VISA-associated ... [more]
