Cytoplasmic Ribonucleoprotein Granules
Definitions related to processing bodies:
  • (p-body) A focus in the cytoplasm where mRNAs may become inactivated by decapping or some other mechanism. Protein and RNA localized to these foci are involved in mRNA degradation, nonsense-mediated mRNA decay (NMD), translational repression, and RNA-mediated gene silencing.

  • Cytoplasmic RNP granules constitutively found in eukaryotic cells. Various proteins related to RNA regulation including RNA decay are found in P-bodies. P-bodies and STRESS GRANULES both sequester inactive mRNPs via different pathways. In P-bodies mRNAs from the stalled translational machinery are deadenylated and condensed for sequestration.
