Modulation of transforming growth factor type beta action by activated ras and c-myc.

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 y...
