Stress granules (SGs) are cytoplasmic structures found in eukaryotic cells, from yeast to human cells. They are made up of proteins, RNA and small ribosome subunits (40S). They arise as a result of the rapid shutdown of active protein biosynthesis in the cell, which is the result of the appearance of a stress factor. The mechanism of regulation of protein biosynthesis in response to stress takes place at two control nodes: (1) phosphorylation of the
