Summary: Enables ATP hydrolysis activity; phosphatidylserine binding activity; and unfolded protein binding activity. Involved in several processes, including clathrin coat disassembly; late endosomal microautophagy; and positive regulation by host of viral genome replication. Acts upstream of or within chaperone cofactor-dependent protein refolding; positive regulation of mRNA splicing, via spliceosome; and regulation of cell cycle. Located in several cellular components, including extracellular exosome; late endosome; and perinuclear region of cytoplasm. Is active in several cellular components, including glycinergic synapse; photoreceptor ribbon synapse; and postsynaptic specialization membrane. Is expressed in several structures, including 1st branchial arch mandibular component; alimentary system; brain; eye; and forelimb long bone. Human ortholog(s) of this gene implicated in Parkinson's disease and renal hypertension. Orthologous to human HSPA8 (heat shock protein family A (Hsp70) member 8).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
