Target intelligence / Profile preview

Heat shock protein 70 kDa 1A (HSPA1A)

Target
HSPA1A
Molecular classification
Molecular chaperone, Heat shock protein
01

Overview

Heat shock protein 70 kDa 1A (Hsp72/HSPA1A) is an essential cytosolic chaperone that safeguards cells from proteotoxic stress through its roles in folding/refolding polypeptides and targeting damaged proteins for degradation. Its dysregulation contributes to diverse human diseases including cancer and neurodegeneration; it also serves potential biomarker functions due to its inducible expression profile under pathological conditions.
