Matrix Metalloproteinases (MMPs) are a large family of endopeptidases. Collectively, MMPs can degrade all kinds of extracellular matrix proteins, and can also process a number of bioactive molecules. They are known to be involved in the cleavage of cell surface receptors, the release of apoptotic ligands, and chemokine/cytokine inactivation. MMPs are also thought to play a major role in cell behaviors such as cell proliferation, migration (adhesion/dispersion), differentiation, angiogenesis, apoptosis, and host defense. This peptide has an optimized sequence for MMP-7, with the cleavage occuring at the Ala-Leu bond. The substrate is used for high throughput screening of MMP-7 inhibitors. Abs/Em = 340/490 nm.
