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.

The nuclear DEAD box RNA helicase p68 interacts with the nucleolar protein fibrillarin and colocalizes specifically in nascent nucleoli during telophase.

Nicol SM, Causevic M, Prescott AR, Fuller-Pace FV

The DEAD box protein, p68, is an established RNA-dependent ATPase and RNA helicase in vitro, but neither the physiological function of this protein nor the macromolecules with which it interacts are known. Using a yeast two-hybrid screen, we identified the nucleolar protein, fibrillarin, as a protein that interacts with p68. Coimmunoprecipitation experiments confirmed that p68 and fibrillarin can form complexes ... [more]
