This gene encodes a mitochondrially localized enzyme that catalyzes the reversible formation of acetoacetyl-CoA from two molecules of acetyl-CoA. Defects in this gene are associated with 3-ketothiolase deficiency, an inborn error of isoleucine catabolism characterized by urinary excretion of 2-methyl-3-hydroxybutyric acid, 2-methylacetoacetic acid, tiglylglycine, and butanone.

GeneCards Summary for ACAT1 Gene
ACAT1 (Acetyl-CoA Acetyltransferase 1) is a Protein Coding gene. Diseases associated with ACAT1 include Alpha-Methylacetoacetic Aciduria and Ataxia-Telangiectasia. Among its related pathways are Carbon metabolism and Terpenoid backbone biosynthesis. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and transferase activity, transferring acyl groups other than amino-acyl groups. An important paralog of this gene is ACAT2.
UniProtKB/Swiss-Prot Summary for ACAT1 Gene
This is one of the enzymes that catalyzes the last step of the mitochondrial beta-oxidation pathway, an aerobic process breaking down fatty acids into acetyl-CoA (PubMed:1715688, PubMed:7728148, PubMed:9744475). Using free coenzyme A/CoA, catalyzes the thiolytic cleavage of medium- to long-chain 3-oxoacyl-CoAs into acetyl-CoA and a fatty acyl-CoA shortened by two carbon atoms (PubMed:1715688, PubMed:7728148, PubMed:9744475). The activity of the enzyme is reversible and it can also catalyze the condensation of two acetyl-CoA molecules into acetoacetyl-CoA (PubMed:17371050). Thereby, it plays a major role in ketone body metabolism (PubMed:17371050, PubMed:1715688, PubMed:7728148, PubMed:9744475).
