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.

A family of diverse Cul4-Ddb1-interacting proteins includes Cdt2, which is required for S phase destruction of the replication factor Cdt1.

Cul4 E3 ubiquitin ligases contain the cullin 4 scaffold and the triple beta propeller Ddb1 adaptor protein, but few substrate receptors have been identified. Here, we identify 18 Ddb1- and Cul4-associated factors (DCAFs), including 14 containing WD40 repeats. DCAFs interact with multiple surfaces on Ddb1, and the interaction of WD40-containing DCAFs with Ddb1 requires a conserved "WDXR" motif. DCAF2/Cdt2, which ... [more]
