stress granules

Stress granules are temporary clusters of molecules that form in cells during stressful conditions, such as heat or lack of nutrients. They mainly contain messenger RNA (mRNA) and proteins. When a cell is under stress, it temporarily halts some activities, including protein production, to conserve energy. Stress granules act as storage sites, holding onto mRNA until conditions improve, helping the cell survive. Once the stress passes, these granules disassemble, allowing normal cell functions to resume. They play a key role in managing cellular stress responses and maintaining cell health.
