Collective Learnings of Studies of Stress Granule Assembly and Composition.

Stress granules have gained considerable exposure and interest in recent years. These micron-sized entities, composed of RNA and protein, form following a stress exposure and have been linked to several pathologies. Understanding stress granule function is paramount but has been arduous due to the membraneless nature of these organelles. Several new methodologies have recently been developed to catalogue the protein and RNA composition of stress granules. Collectively, this work has provided important insights to potential stress granule functions as well as molecular mechanisms for their assembly and disassembly. This chapter reviews the latest advancements in the understanding of stress granule dynamics and discusses the various protocols developed to study their composition.
