Predicted to enable long-chain acyl-CoA hydrolase activity; long-chain fatty acyl-CoA binding activity; and palmitoyl-CoA hydrolase activity. Involved in negative regulation of cold-induced thermogenesis. Acts upstream of or within response to cold. Predicted to be located in mitochondrial matrix. Predicted to be active in cytosol. Orthologous to human ACOT11 (acyl-CoA thioesterase 11). [provided by Alliance of Genome Resources, Apr 2022]
