Abstract

Eukaryotic cells contain at least two types of cytoplasmic RNA-protein (RNP) granules that contain nontranslating mRNAs. One such RNP granule is a P-body, which contains translatlonally inactive mRNAs and proteins involved In mRNA degradation and translation repression. A second such RNP granule is a stress granule which also contains mRNAs, some RNA binding proteins and several translation initiation factors, suggesting these granules contain mRNAs stalled in translation initiation. In this chapter, we describe methods to analyze P-bodies and stress granules in Saccharomyces cerevisiae, including procedures to determine if a protein or mRNA can accumulate in either granule, if an environmental perturbation or mutation affects granule size and number, and granule quantification methods.
