CC -!- FUNCTION: Cleaves collagen type I. May play a role in larval tissue
CC degeneration and adult organogenesis during amphibian metamorphosis.
CC May be involved in tail resorption.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Up-regulated in the tail by thyroid hormone.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC matrix {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed only transiently in whole animal, at time
CC when tadpole feeding begins.
CC -!- DEVELOPMENTAL STAGE: Expressed at high level as the tadpole tail
CC resorbs and during hindlimb morphogenesis and intestinal remodeling.
CC -!- DOMAIN: The conserved cysteine present in the cysteine-switch motif
CC binds the catalytic zinc ion, thus inhibiting the enzyme. The
CC dissociation of the cysteine from the zinc ion upon the activation-
CC peptide release activates the enzyme.
CC -!- SIMILARITY: Belongs to the peptidase M10A family. {ECO:0000305}.
