Molecular biology - P-bodies mark the spot for controlling protein production

P-bodies, specks in the cytoplasm, have been shown to play key roles in regulating one of the cells most important activities, protein synthesis. Researchers had thought that once mRNAs had done their job, enzymes in the cytoplasm simply broke them down however, they appear to play a more dynamic role, serving as routing stations that can temporarily store mRNAs before sending them out to be translated into the proteins that cells need.
