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.

RNA sensor LGP2 inhibits TRAF ubiquitin ligase to negatively regulate innate immune signaling.

Parisien JP, Lenoir JJ, Mandhana R, Rodriguez KR, Qian K, Bruns AM, Horvath CM

The production of type I interferon (IFN) is essential for cellular barrier functions and innate and adaptive antiviral immunity. In response to virus infections, RNA receptors RIG-I and MDA5 stimulate a mitochondria-localized signaling apparatus that uses TRAF family ubiquitin ligase proteins to activate master transcription regulators IRF3 and NFκB, driving IFN and antiviral target gene expression. Data indicate that a ... [more]
