matrilysin

matrix metalloproteinase 7

A 19-kD enzyme encoded on chromosome 11q21-q22 which degrades fibronectin, gelatins and other matrix substrates.

Matrilysin (matrix metal loproteinase-7): a new promising drug target in cancer and inflammation?
Matrilysin (MMP7) is a protease with broad substrate specificity, being able to degrade elastin, proteoglycans, fibronectin, and type IV collagen.
These MMPs are divided into five subgroups according to their substrate specificity and structural similarities: Collagenases, stromelysins, gelatinases, matrilysins and membrane-type MMPs (Mook et al.
