Nuclear Recruitment Assay as a Tool to Validate Transcription Factor Interactions in Mammalian Cells
Identification and verification of novel transcription factor interactions is an inherent step in the discovery of molecular mechanisms driving gene transcription and regulation. Co-immunoprecipitation and GST-pull down are often key techniques in the verification process. Despite wide applicability, their use may sometimes be restricted. We provide a detailed protocol for an intracellular immunofluorescence technique that may be used as an alternative or complimentary study for transcription factor interaction verification.
