Abstract

Ydr374c (Pho92) contains a YTH domain in its C-terminal region and is a human YTHDF2 homologue. Previously, we reported that Pho92 regulates phosphate metabolism by regulating PHO4 mRNA stability. In this study, we found that growth of the {increment}pho92 strain on SG media was slower than that of the wild type and that PHO92 expression was up-regulated by non-fermentable carbon sources, such as ethanol and glycerol, but not by fermentable carbon sources. Furthermore, two conserved Gcr1-binding regions were identified in the upstream, untranslated region of PHO92. Gcr1 is an important factor involved in the coordinated regulation of glycolytic gene expression. Mutation of two Gcr1-binding sites of the PHO92 upstream region resulted in a growth defect on SD media. Finally, mutagenesis of the Gcr1-binding sites of the PHO92 upstream region and deletion of GCR1 resulted in up-regulation of PHO92, and this resulted from inhibition of PHO4 mRNA degradation. Based on these results, we suggest that Gcr1 regulates the expression of PHO92, and Pho92 is involved in glucose metabolism.
