Anti-SOAT2 antibodies are used in the immunodetection of the protein sterol O-acyltransferase 2. In humans, the canonical protein has a reported length of 522 amino acid residues and a mass of 59.9 kDa. Its subcellular localization is in the ER. Up to 4 different isoforms have been reported for this protein. A member of the Membrane-bound acyltransferase protein family, Soat2 is known to catalyze the formation of fatty acid-cholesterol esters, which are less soluble in membranes than cholesterol. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include ACAT2, ARGP2, ACAT-2, acyl Co-A: cholesterol acyltransferase 2, acyl coenzyme A:cholesterol acyltransferase 2, and ACACT2. SOAT2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of Soat2 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
