Predicted to enable peptidase activity and protease binding activity. Predicted to be involved in protein processing; protein targeting to peroxisome; and regulation of fatty acid beta-oxidation. Predicted to act upstream of or within proteolysis. Located in cytoplasm and nucleus. Is expressed in future brain; future prosencephalon; head; neural tube; and remnant of Rathke's pouch. Orthologous to human LONP2 (lon peptidase 2, peroxisomal). [provided by Alliance of Genome Resources, Apr 2022]
