MMP2 is an extracellular matrix degradative peptidase enzyme that belongs to the large family of matrix metalloproteinases (MMPs) which each have different substrate specificities. Aberrant or derailed expression of various MMPs through loss of negative checks is strongly associated with tumor invasion, metastasis, and angiogenesis, as compared to tightly controlled physiological processes such as tissue remodeling, rebuilding, and embryonic development.
