General description

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.

Immunogen

Acetyl-CoA acetyltransferase, mitochondrial precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-ACAT1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . 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.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
