This book covers various state-of-the-art techniques regarding the associations between transcription factors (TFs) and genes, with a focus on providing methodological and practical references for researchers. The contents cover diverse protocols and summaries of TFs including screening of TF-DNA interactions, detection of open chromatin regions, identification of epigenetic regulations, engineering TFs with genome editing tools, detection of transcriptional activities, computational analysis of TF networks, functions and druggabilities of TFs in biomedical research, and much more. Written for the highly successful Methods in Molecular Biology series, chapters feature the kind of detailed implementation advice from the experts to ensure successful research results.
