Transcriptional activators coordinate the dynamic assembly of multiprotein coactivator complexes required for gene expression to occur. Here we combine the power of in vivo covalent chemical capture with p-benzoyl-L-phenylalanine (Bpa), a genetically incorporated photo-crosslinking amino acid, and chromatin immunoprecipitation (ChIP) to capture the direct protein interactions of the transcriptional activator VP16 with the general transcription factor TBP at the GAL1 promoter in live yeast.
