Predicted to enable ATP hydrolysis activity; heat shock protein binding activity; and protein folding chaperone. Predicted to be involved in chaperone cofactor-dependent protein refolding and protein refolding. Predicted to be active in cytosol; nucleus; and plasma membrane. Human ortholog(s) of this gene implicated in several diseases, including Kawasaki disease; autoimmune disease of musculoskeletal system (multiple); cystic fibrosis; schizophrenia (multiple); and toxic shock syndrome. Orthologous to several human genes including HSPA1L (heat shock protein family A (Hsp70) member 1 like); HSPA1A (heat shock protein family A (Hsp70) member 1A); and HSPA1B (heat shock protein family A (Hsp70) member 1B).
