Predicted to enable protein-folding chaperone binding activity. Acts upstream of or within several processes, including fin regeneration; regulation of neutrophil chemotaxis; and regulation of organelle organization. Located in mitochondrial matrix. Is expressed in several structures, including anterior neural keel; digestive system; mesoderm; musculature system; and nervous system. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autistic disorder; glucose intolerance; hereditary spastic paraplegia (multiple); and hypomyelinating leukodystrophy 4. Orthologous to human HSPD1 (heat shock protein family D (Hsp60) member 1).
