The 56kDa protein ACAT1 (acetyl-CoA acetyltransferase 1) is majorly involved in the cellular cholesterol homeostasis. It belongs to the membrane-bound O-acyltransferase family, presents in various cell types. In mammals, ACAT1 exists in two isoenzyme form: ACAT1 and ACAT2. It is composed of nine transmembrane domains (TMDs), with two active sites. One active site His460, is located within TMD7 and the second active site Asn421, is located within the fourth large cytoplasmic loop.
Synonyms: ACAT; THIL

Application: Anti-ACAT1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: ACAT1 (acetyl-CoA acetyltransferase 1) is highly involved in the ketogenic pathway. It accelerates the conversion of cholesterol to cholesteryl esters. The elevated level of the protein expression has been observed in the prostate cancer. Thus, it acts as a potential prognostic marker in prostate cancer.
