MMP3

Domain

The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.

Function

Can degrade fibronectin, laminin, gelatins of type I, III, IV, and V; collagens III, IV, X, and IX, and cartilage proteoglycans. Activates procollagenase.

Involvement in disease

Coronary heart disease 6

CHDS6

A multifactorial disease characterized by an imbalance between myocardial functional requirements and the capacity of the coronary vessels to supply sufficient blood flow. Decreased capacity of the coronary vessels is often associated with thickening and loss of elasticity of the coronary arteries.

None

Disease susceptibility is associated with variants affecting the gene represented in this entry. A polymorphism in the MMP3 promoter region is associated with the risk of coronary heart disease and myocardial infarction, due to lower MMP3 proteolytic activity and higher extracellular matrix deposition in atherosclerotic lesions.

Sequence similarities

Belongs to the peptidase M10A family.
