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.

Nardilysin facilitates complex formation between mitochondrial malate dehydrogenase and citrate synthase.

Chow KM, Ma Z, Cai J, Pierce WM, Hersh LB

Gel filtration chromatography showed that nardilysin activity in a rat testis or rat brain extract exhibited an apparent molecular weight of approximately 300 kDa compared to approximately 187 kDa for the purified enzyme. The addition of purified nardilysin to a rat brain extract, but not to an E. coli extract, produced the higher molecular species. The addition of a GST ... [more]

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.
