Pdc1 functions in the assembly of P bodies in Schizosaccharomyces pombe.

ABSTRACT: P bodies are cytoplasmic RNA granules containing the Dcp1-Dcp2 decapping enzymes where mRNA decay can occur. Here, we describe the characterization of P bodies in the fission yeast Schizosaccharomyces pombe. Most information on the property and function of P bodies stems from studies in the distantly related budding yeast Saccharomyces cerevisiae, and Edc3 was identified as a scaffold protein required for P-body assembly. However, we found that, unlike in S. cerevisiae, fission yeast Edc3 was dispensable for P-body formation. Pdc1, a novel partner of the fission yeast decapping enzyme, with a limited similarity to plant Edc4/Varicose that is required for the assembly of P bodies, was identified (tandem affinity purification-matrix-assisted laser desorption ionization tandem mass spectromet
