Enables several functions, including acetyl-CoA C-acetyltransferase activity; coenzyme A binding activity; and identical protein binding activity. Involved in several processes, including animal organ development; response to hormone; and response to starvation. Located in mitochondrial matrix. Biomarker of end stage renal disease and nephrotic syndrome. Human ortholog(s) of this gene implicated in beta-ketothiolase deficiency and carbohydrate metabolic disorder. Orthologous to human ACAT1 (acetyl-CoA acetyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
