Dual-initiation promoters with intertwined canonical and TCT/TOP transcription start sites diversify transcript processing
Abstract
The functional significance of start site choice in promoter architectures is little understood. Here the authors identify in zebrafish development and mammalian cells a class of dual-initiation promoters, in which non-canonical YC dinucleotides reflecting 5’-TOP/TCT initiation are intertwined with canonical YR-initiation.
