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.

Characterization of the neuronal targeting protein spinophilin and its interactions with protein phosphatase-1.

Hsieh-Wilson LC, Allen PB, Watanabe T, Nairn AC, Greengard P

Protein phosphatase-1 (PP1) plays an important role in a variety of cellular processes, including muscle contraction, cell-cycle progression, and neurotransmission. The localization and substrate specificity of PP1 are determined by a class of proteins known as targeting subunits. In the present study, the interaction between PP1 and spinophilin, a neuronal protein that targets PP1 to dendritic spines, has been characterized. ... [more]
