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.

Mechanism of client selection by the protein quality-control factor UBE2O.

Yip MCJ, Sedor SF, Shao S

The E2/E3 enzyme UBE2O ubiquitylates diverse clients to mediate important processes, including targeting unassembled 'orphan' proteins for quality control and clearing ribosomes during erythropoiesis. How quality-control factors, such as UBE2O, select clients on the basis of heterogeneous features is largely unknown. Here, we show that UBE2O client selection is regulated by ubiquitin binding and a cofactor, NAP1L1. Attaching a single ... [more]
