FunctionMay play an important role in the progression of epithelial malignancies.
Tissue specificitySpecifically expressed in stromal cells of breast carcinomas.
Sequence similaritiesBelongs to the peptidase M10A family. Contains 4 hemopexin-like domains.
DomainThe 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.
Post-translational modificationsThe precursor is cleaved by a furin endopeptidase.
