Bz-Arg-Gly-Phe-Phe-Pro-4MbNA is a fluorogenic substrate for Cathepsin D. Cathepsin D is a lysosomal aspartyl protease whose role is to degrade and activate intracellular proteins including hormones, enzyme precursors, and growth factors. Over expression in tumors stimulates metastasis and considered a marker of poor prognosis in breast cancer.
Activity is quantified by release of free fluorescent 4-Methoxy-β-naphthylamine (4MβNA) which excites at 335-350 nm and emits at 410-440 nm.
