Stress granules

Last changed: 30 October 2021

Stress granules are transient membraneless organelles which are formed in eukaryotic cells in response to stress. They are composed of messenger ribonucleoprotein complexes, have core-shell substructure and are essential for regulating the rate of protein translation and signalling under stress, with important implications for cancer and neurodegenerative diseases. Our current efforts are to unravel molecular structure of stress granules and their biochemical role in plant development and fitness.
