Enables several functions, including 1-acylglycerol-3-phosphate O-acyltransferase activity; long-chain fatty acyl-CoA binding activity; and lysophosphatidic acid binding activity. Involved in glycerolipid metabolic process; long-chain fatty acid metabolic process; and response to dietary excess. Located in lipid droplet and membrane. Is expressed in left lung; olfactory epithelium; and right lung. Used to study non-alcoholic fatty liver disease. Human ortholog(s) of this gene implicated in coronary artery disease; fatty liver disease (multiple); liver disease (multiple); and type 2 diabetes mellitus. Orthologous to human PNPLA3 (patatin like phospholipase domain containing 3). [provided by Alliance of Genome Resources, Apr 2022]
