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 E3 ubiquitin ligase Nrdp1 'preferentially' promotes TLR-mediated production of type I interferon.

Wang C, Chen T, Zhang J, Yang M, Li N, Xu X, Cao X

E3 ubiquitin ligases are important in both innate and adaptive immunity. Here we report that Nrdp1, an E3 ubiquitin ligase, inhibited the production of proinflammatory cytokines but increased interferon-beta production in Toll-like receptor-triggered macrophages by suppressing adaptor MyD88-dependent activation of transcription factors NF-kappaB and AP-1 while promoting activation of the kinase TBK1 and transcription factor IRF3. Nrdp1 directly bound and ... [more]
