HSPA9A gene on chromosome 5q31.1 that encodes a member of the heat shock protein 70 (HSP70) family which localises to the mitochondria as well as the endoplasmic reticulum, plasma membrane and cytoplasmic vesicles. HSPA9 plays a role in cell proliferation, stress response and maintenance of mitochondria; it may play a role in controlling cell proliferation and ageing and act as a chaperone.
