The Saccharomyces cerevisiae dual-specificity protein phosphatase Yvh1p, identified as vaccinia VH1 homolog, regulates cell growth, sporulation, and glycogen accumulation. Transcription of YVH1 is induced by lowering temperature and nitrogen starvation. Using the yeast two-hybrid system, we searched for Yvh1p-interacting proteins, including substrates and regulatory subunits of Yvh1p. Two clones were identified encoding a segment of YPH1 (yeast pescadillo homolog), which is essential for cell cycle progression in yeast. Deletion analysis revealed that the catalytic domain of Yvh1p and the BRCT domain of Yph1p are sufficient for this interaction. We found that the multicopy of YPH1 not only suppressed slow growth but also decreased IME2 expression in the yvh1 disruptant. These observations indicate that Yph1p plays a role in sporulation in addition to cell cycle progression, and is a candidate for a substrate or a regulatory subunit of Yvh1p.
