    Summary
    Enables unfolded protein binding activity. Involved in SRP-dependent cotranslational protein targeting to membrane, translocation and protein folding. Located in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in several diseases, including Kawasaki disease; artery disease (multiple); autoimmune disease of musculoskeletal system (multiple); neurodegenerative disease (multiple); and schizophrenia (multiple). Orthologous to several human genes including HSPA1B (heat shock protein family A (Hsp70) member 1B) and HSPA8 (heat shock protein family A (Hsp70) member 8).
