General annotation (Comments)

Function

May have an important and specific function in tumor progression and embryogenesis. Cleaves alpha-1-antitrypsin By similarity.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Calcium By similarity.

Subcellular location

Secreted Potential.

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.

Post-translational modification

The precursor is cleaved by a furin endopeptidase By similarity.

Sequence similarities

Belongs to the peptidase M10A family.

Contains 4 hemopexin-like domains.
