Predicted to enable hydrolase activity. Acts upstream of or within modulation of chemical synaptic transmission; neuromuscular process controlling posture; and regulation of dopamine metabolic process. Located in mitochondrion. Is expressed in central nervous system and retina. Used to study paroxysmal nonkinesigenic dyskinesia 1. Human ortholog(s) of this gene implicated in paroxysmal nonkinesigenic dyskinesia 1. Orthologous to human PNKD (PNKD metallo-beta-lactamase domain containing). [provided by Alliance of Genome Resources, Apr 2022]
