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.

Identification of a rabphilin-3A-interacting protein as GTP cyclohydrolase I in PC12 cells.

Imazumi K, Sasaki T, Takahashi K, Takai Y

Rabphilin-3A is a putative target protein for Rab3A small GTP-binding protein which is implicated in neurotransmitter release. To identify a Rabphilin-3A-interacting protein, proteins were immunoprecipitated by an anti-Rabphilin-3A polyclonal antibody from the lysate of PC12 cells and subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis followed by protein staining. Several proteins were coimmunoprecipitated with Rabphilin-3A and one of these proteins ... [more]
