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.

Human CWC22 escorts the helicase eIF4AIII to spliceosomes and promotes exon junction complex assembly.
The exon-junction complex (EJC) functionally links splicing to subsequent mRNA localization, translation and stability. Sequence-independent binding of the EJC core to RNA is ensured by the DEAD-box helicase eIF4AIII. Here, we identified the splicing factor CWC22 as a new eIF4AIII partner in flies and humans. CWC22 coexists with eIF4AIII in large protein complexes distinct from EJCs. Recombinant CWC22 directly contacts ... [more]
