The Legionella pneumophila effector PieF modulates mRNA stability through association with eukaryotic CCR4−NOT by Harley O'Connor Mount, Malene L. Urbanus, Francesco Zangari, Anne-Claude Gingras, Alexander W. Ensminger

“…Heterologous expression of PieF phenocopies knockout of the CNOT7 ortholog (POP2) in Saccharomyces cerevisiae, resulting in 6-azauracil sensitivity. In mammalian cells, expression of PieF leads to a variety of quantifiable phenotypes: PieF silences gene expression and reduces mRNA steady-state levels when artificially tethered to a reporter transcript, and its overexpression results in the nuclear exclusion of CNOT7. …”
