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.

Autophagy-dependent clearance of ubiquitinated and aggregated proteins is critical to protein quality control, but the underlying mechanisms are not well understood. Here, we report the essential role of the BEACH (beige and Chediak-Higashi) and WD40 repeat-containing protein WDR81 in eliminating ubiquitinated proteins through autophagy. WDR81 associates with ubiquitin (Ub)-positive protein foci, and its loss causes accumulation of Ub proteins and ... [more]
