功能Can degrade fibrillar type I, II, and III collagens.
序列相似性Belongs to the peptidase M10A family. Contains 4 hemopexin-like domains.
结构域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.
细胞定位Cytoplasmic granule. Secreted > extracellular space > extracellular matrix. Stored in intracellular granules.
