Predicted to enable acetyl-CoA C-acetyltransferase activity. Involved in positive regulation of intestinal cholesterol absorption. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in coronary artery disease. Orthologous to human ACAT2 (acetyl-CoA acetyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
