ABSTRACT

Transcriptional changes happen within minutes; however, RNAi or genetic deletion requires days to weeks before transcription networks can be analyzed. This limitation has made it challenging to distinguish direct from indirect targets of sequence-specific transcription factors. This inability to define direct transcriptional targets hinders detailed studies of transcriptional mechanisms. This protocol combines rapid degradation of endogenous transcription factors with nascent transcript analysis to define the earliest, and likely direct, regulatory targets of transcription factors. For complete details on the use and execution of this protocol, please refer to Stengel et al., 2021).
