Predicted to enable ATP hydrolysis activity; heat shock protein binding activity; and protein folding chaperone. Involved in mitochondrial unfolded protein response. Located in mitochondrion. Expressed in muscle cell. Human ortholog(s) of this gene implicated in Alzheimer's disease; Parkinson's disease; autosomal dominant sideroblastic anemia 4; and rheumatoid arthritis. Is an ortholog of human HSPA9 (heat shock protein family A (Hsp70) member 9).
This gene encodes a member of the heat shock protein 70 gene family. The encoded protein is primarily localized to the mitochondria but is also found in the endoplasmic reticulum, plasma membrane and cytoplasmic vesicles. This protein is a heat-shock cognate protein. This protein plays a role in cell proliferation, stress response and maintenance of the mitochondria. A pseudogene of this gene is found on chromosome 2.[provided by RefSeq, May 2010]
