The precise nature of antisense transcripts in eukaryotes such as Saccharomyces cerevisiae remains elusive. Here we show that the 3' regions of genes possess a promoter architecture, including a pre-initiation complex (PIC), which mirrors that at the 5' region and which is much more pronounced at genes with a defined antisense transcript. Remarkably, for genes with an antisense transcript, average levels of PIC components at the 3' region are ∼60% of those at the 5' region. Moreover, at these...Expand abstract

A pre-initiation complex at the 3'-end of genes drives antisense transcription independent of divergent sense transcription.
