Analysis Note

The biological activity is measured by its ability to cleave a fluorogenic peptide sustrate.

Application

Matrix metalloproteinase-2 (MMP2) human has been used as a standard in zymography to measure proteolytic activity of MMP-2.

Biochem/physiol Actions

Matrix Metalloproteinase-2 (MMP-2) cleaves gelatin, type IV, V, VII, X, and XI collagens, fibronectin, elastin, laminin, proteoglycans and a range of non extracellular matrix (ECM ) components. MMP-2 cleaves native type I collagen to N-terminal ¾ and C-terminal ¼ fragments identical to those generated by interstitial collagenases. MMP2 and MMP9 play an essential role in matrix degradation and they are implicated in the maintenance of neovascularization. In mice, deletion or inhibition of MMP2 protects against myocardial rupture.

MMP-2 degrades general matrix components and may have a role in processes such as host defense, cell proliferation, and protein turnover as well as tissue remodeling.

General description

Matrix Metalloproteinase-2 (MMP-2) also known as gelatinase or type IV collagenase is a 72kDa protein. MMP-2 is a member of matrix metalloproteinase (MMP) family of enzymes. Basic structure of MMP2 contains signal peptide domain that targets the enzyme for secretion, the pro-peptide domain, which is removed when the enzyme is activated and the catalytic site containing gelatin-binding domain.
