Functioni

Acyl-CoA thioesterases are a group of enzymes that catalyze the hydrolysis of acyl-CoAs to the free fatty acid and coenzyme A (CoASH), providing the potential to regulate intracellular levels of acyl-CoAs, free fatty acids and CoASH. Has acyl-CoA thioesterase activity towards medium (C12) and long-chain (C18) fatty acyl-CoA substrates. Can also hydrolyze 3-hydroxyphenylacetyl-CoA (in vitro). May play a role in controlling adaptive thermogenesis.2 Publications

    Disruption phenotypei

    No visible phenotype until 7 weeks of age. Animals are viable and fertile. After 7 weeks, mutant mice exhibit a modest decrease in body weight and decreased adiposity, compared to wild-type animals, despite increased food consumption. They tend to show a reduced hepatic fatty acyl-CoA thioesterase activity, leading to alterations in fatty acid metabolism and improved glucose homeostasis. When fed a high-fat diet, mutant livers are protected against steatosis and increased hepatic glucose production (PubMed:22345407). Mutant mice adapt more rapidly than wild-type to short-term cold exposure by increasing physical activity, food consumption and energy expenditure. After 96-hour equilibration at cold temperature, genotype-dependent differences are abolished. Mutant brown adipose tissue show reduced lipid droplets, alterations in the ultrastructure of mitochondria and a small increase in the expression of thermogenic genes (PubMed:24072708).2 Publications
