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.

Direct interaction between transcription factors may provide a mechanism for the regulatory function of these proteins on transcription of the responsive genes. These interactions may be facilitated if the target DNA sequences for the participant regulatory proteins are overlapped or positioned in close proximity to each other within the promoter of the responsive genes. In earlier studies, we identified a ... [more]
