Cayman SOAT-2/ACAT-2 Polyclonal Antibody

Sterol O-acyltransferase 2 (SOAT-2), also known as acyl-coenzyme A:cholesterol acyltransferase-2 (ACAT-2), is an enzyme encoded by ACAT2 in humans that catalyzes the intracellular formation of cholesterol esters from cholesterol and long-chain fatty acyl-coenzyme A. It is constitutively expressed in the liver and small intestine and localized to the rough endoplasmic reticulum where it preferentially utilizes oleic acid (Item Nos. | ) or palmitic acid (Item No. ) as fatty acid substrates for the synthesis of cholesterol esters, which are stored intracellularly or packaged into chylomicrons or VLDL and secreted into the blood stream. SOAT-2/ACAT-2 protein levels are increased in macrophages under various pathological conditions, including atherosclerosis. SOAT-2/ACAT-2 activity and protein levels are increased by cholesterol in vitro and in vivo, and ACAT2 expression is increased by the transcription factors hepatocyte nuclear factor 1-α (HNF-1-α) and HNF-4-α in Caco-2 cells and human liver, respectively. Genome-wide deletion of Acat2 reduces intestinal cholesterol absorption and decreases hepatic, but not plasma, total cholesterol levels in mice fed a high-cholesterol diet. Liver ACAT2 activity is negatively correlated with plasma HDL-C and ApoA1 in normolipidemic patients. Caymans SOAT-2/ACAT-2 Polyclonal Antibody can be used for immunofluorescence (IF), immunohistochemistry (IHC), and Western blot (WB) applications. The antibody recognizes the N-terminal region of SOAT-2/ACAT-2 at approximately 60 kDa from human, mouse, ovine, porcine, and rat samples.
