Alternative TSS usage is pervasive in organismal development, is a major contributor to transcript isoform diversity in humans, and is frequently observed in human diseases including cancer. In this review, we discuss the breadth of techniques that have been used to globally profile TSSs and the resulting insights into gene regulation, as well as future prospects in this area of inquiry.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalTranscription start site (TSS)TranscriptionTranscription initiationTranscriptomePromoterArticle
