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.

Combinatorial gene control involving E2F and E Box family members.

Giangrande PH, Zhu W, Rempel RE, Laakso N, Nevins JR

Various studies point to the potential role of combinatorial action of transcription factors as a mechanism to achieve the complexity of eukaryotic gene control with a finite number of regulatory proteins. Our previous work has focused on interactions involving the E2F family of transcription factors as an example of combinatorial gene control, leading to the identification of TFE3 and YY1 ... [more]

Co-localization
Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.
