Summary: Enables protein-folding chaperone binding activity. Involved in several processes, including axon development; late endosomal microautophagy; and regulatory ncRNA-mediated gene silencing. Located in cytosol and nucleus. Part of catalytic step 2 spliceosome and precatalytic spliceosome. Is expressed in several structures, including adult brain; adult head; adult heart; embryonic/larval neuromuscular junction; and ovary. Human ortholog(s) of this gene implicated in Parkinson's disease and renal hypertension. Orthologous to several human genes including HSPA8 (heat shock protein family A (Hsp70) member 8).
