stromelysin

(strō′mă-līs-ĭn),

MMP-3

Member of the matrix metalloproteinase family of enzymes that plays a major role in the degradation of proteoglycans, gelatin, and other constituents of the extracellular matrix. Two forms of stromelysin have been described, stromelysin-1 and -2. Stromelysin-1 degrades proteoglycans, gelatin, fibronectin, laminin, collagen types III, IV, IX, and X. Stromelysin-2 degrades proteoglycans, fibronectin, laminin, and collagen type IV.
