AMACR, also known as P504S, is an enzyme that is involved in bile acid biosynthesis and β-oxidation of branched-chain fatty acids. It is expressed in cells of premalignant high-grade prostatic intraepithelial neoplasia (HGPIN) and prostate adenocarcinoma (1). In glandular epithelial cells of normal and benign hyperplastic prostates AMACR is present at low or undetectable levels.
