Predicted to enable hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides. Predicted to be involved in several processes, including energy homeostasis; negative regulation of neuron death; and regulation of oxidative phosphorylation uncoupler activity. Predicted to be located in extracellular space. Orthologous to human PM20D1 (peptidase M20 domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
