Enables protein folding chaperone. Involved in lysosomal transport and protein folding. Acts upstream of or within DNA repair; response to heat; and telomere maintenance. Located in cytoplasm. Is expressed in several structures, including adrenal gland; early conceptus; genitourinary system; and vibrissa. 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 HSPA1B (heat shock protein family A (Hsp70) member 1B). [provided by Alliance of Genome Resources, Apr 2022]
