    ..Altogether, these results should facilitate future studies on which of the many functions of Puf3p is most relevant for regulating mitochondrial gene expression and the role of nuclear-mitochondrial communication in aging and longevity. ..

    A single regulatory protein can control the fate of many mRNAs with related functions. The Puf3 protein of Saccharomyces cerevisiae is exemplary, as it binds and regulates more than 100 mRNAs that encode proteins with mitochondrial ..
