Regulation by the homologous Ace2 and Swi5 factors of Saccharomyces cerevisiae

ABSTRACT: The homologous Ace2 and Swi5 transcription factors of Saccharomyces cerevisiae have identical DNA-binding domains, and both are cell cycle regulated. There are common target genes, as well as genes activated only by Ace2 and other genes activated only by Swi5. Keywords: genetic modification RNA was isolated from four strains: wild type, ace2 gene deletion, swi5 gene deletion, and the ace2 swi5 double gene deletion. RNAs from the three mutant strains were compared to wild type RNA in a microarray hybridization experiment.

Transcription factors with identical DNA-binding specificity often activate different genes in vivo. Yeast Ace2 and Swi5 are such activators, with targets we classify as Swi5-only, Ace2-only, or both. We define two unique regulatory modes. Ace2 and Swi5 both bind in vitro to Swi5-only genes such as HO, but only Swi5 binds and activates in vivo. In contrast, Ace2 and Swi5 both bind in vivo to Ace2-only genes, such as CTS1, but promoter-bound Swi5 fails to activate. We show that activation by Swi5  ...[more]
