Biochem/physiol Actions

Hspa4 (heat shock protein family A (Hsp70) member 4) is an important ATP-dependent cytosolic chaperone along with Hsp90. Hspa4 aids in the folding of several proteins and helps in protecting against cellular stresses such as rise in temperature. Hspa4 maintains the function of the mitotic centrosome to coordinates bipolar mitotic spindle assembly. Hspa4 might compensate the loss of parkin function in mice by protecting the cells against proteolytic and mitochondrial stress. Therefore, it can serve as an important therapeutic agent for parkinson disease. Upregulation of HSPA4 is observed in parkin gene knockout mice. Hspa4 is known to be associated with tumor progression and offers resistance against many therapeutic agents. The gene is upregulated in many different types of cancer.
