Predicted to enable carboxylic ester hydrolase activity. Predicted to be involved in medium-chain fatty acid biosynthetic process; medium-chain fatty acid catabolic process; and phosphatidylcholine metabolic process. Is expressed in brain; intestinal bulb; lateral line ganglion; and otic vesicle. Orthologous to human ABHD3 (abhydrolase domain containing 3, phospholipase).
