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.
