Abstract
|
|
|
|
RNA granules such as Stress Granules (SG) and P-Bodies (PB) are aggregates of translationally stalled messenger ribonucleoprotein (mRNP) complexes induced by a wide range of stresses. Over the past decade, extensive studies described key components of RNA granules, their molecular interactions and signaling pathways require for their assembly and disassembly. However, researches defining their exact roles under stress conditions have not been performed so far, although several studies suggested their roles in neurodegenerative diseases recently. In this review, we provide an introduction about their basic properties, key components, and the dynamic nature for their assembly.
