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.

Physical interactions between proteins are essential for biological processes. Hence, there have been major efforts to elucidate the complete networks of protein-protein interactions, or 'interactomes', of various organisms. Detailed descriptions of protein interaction networks should include information on the discrete domains that mediate these interactions, yet most large-scale efforts model interactions between whole proteins only. We previously developed a yeast ... [more]
