General annotation (Comments)

Function	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. May play an important physiological function in brain. May play a regulatory role by modulating the cellular levels of fatty acyl-CoA ligands for certain transcription factors as well as the substrates for fatty acid metabolizing enzymes, contributing to lipid homeostasis. Has broad specificity, active towards fatty acyl-CoAs with chain-lengths of C8-C18. Has a maximal activity toward palmitoyl-CoA.
Catalytic activity	Palmitoyl-CoA + H(2)O = CoA + palmitate.
Subunit structure	Homodimer Probable.
Subcellular location	Isoform 4: Cytoplasm. Isoform 6: Cytoplasm. Isoform 1: Mitochondrion. Isoform 5: Mitochondrion.
Tissue specificity	Isoform 4 is expressed exclusively in brain.
Sequence similarities	Contains 2 acyl coenzyme A hydrolase domains.
Sequence caution	The sequence AAB61211.1 differs from that shown. Reason: Frameshift at position 371.
