P-bodies

The processing bodies (also called GW or Dcp bodies) are microscopic structures within the eukaryotic cell, made up of many enzymes involved in mRNA turnover and reclute many mRNAs, which become unavailable for the translational machinery.

The following activities of p-bodies were demonstrated:
 * degrade unwanted mRNAs that lack a 5' cap
 * store mRNA until needed for translation
 * aid in translational repression by miRNAs (related to siRNAs)
