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.

Proteomic identification of a PSF/p54nrb heterodimer as RNF43 oncoprotein-interacting proteins.

Miyamoto K, Sakurai H, Sugiura T

RNF43 is an oncogenic RING finger protein overexpressed in colorectal cancer. To dissect its biological functions, we explored RNF43-interacting proteins by pull-down assay and MS. We identified a heterodimer, p54nrb and PSF, as RNF43's binding partners and confirmed their physical interaction in vivo by the co-immunoprecipitation experiment. Immunofluorescence analysis revealed that co-expression of PSF relocates RNF43 from the nuclear periphery ... [more]
