Predicted to enable palmitoyl-CoA hydrolase activity. Predicted to be involved in acyl-CoA metabolic process; fatty acid metabolic process; and response to hypoxia. Predicted to act upstream of or within lipid metabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Orthologous to human ACOT1 (acyl-CoA thioesterase 1) and ACOT2 (acyl-CoA thioesterase 2). [provided by Alliance of Genome Resources, Apr 2022]
