Proteomic and transcriptomic analyses of Dhh1 complexes reveals mitochondrial RNP complex association with yeast P-bodies
Ontology highlight
ABSTRACT: P-bodies (PB) are cytoplasmic RNP complexes that aggregate into foci when cells are exposed to stress. While the core components and stress response of PB and related RNP granules are conserved, it remains unclear how and why cells assemble mRNP complexes into granule foci during stress. We use mass spectrometry and antibody-based microarray to analyze proteins and RNA, respectively, that are immunoisolated with the core PB protein Dhh1-GFP. Analysis of the RNA associated with Dhh1-GFP immunoisolate reveals an enrichment of mitochondrial catalytic RNPs complex, suggesting a role for PB in mitochondrial RNA processing.
