Background
HSP27 (Heat shock protein 27) belongs to the small heat-shock protein (sHSP) family and resides mainly in cytoplasm, forming oligomeric complexes for chaperone activity. It binds denatured polypeptides and prevents irreversible protein aggregation to shield cells from heat shock, oxidative stress and cytotoxic insults. HSP27 participates in cytoskeleton remodeling and anti-apoptotic regulation to control cell survival and migration. Phosphorylation remodels its oligomer assembly and switches biological activities. Elevated HSP27 is frequently detected in multiple malignancies, correlating with metastasis and chemoresistance; it also contributes to inflammation and neuronal injury.
