Protein attributes
| Sequence length | 482 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Degrades amelogenin, the major protein component of the enamel matrix and two of the macromolecules characterizing the cartilage extracellular matrix: aggrecan and the cartilage oligomeric matrix protein (COMP). May play a central role in tooth enamel formation By similarity. |
| Catalytic activity | Cleaves aggrecan at the 360-Asn-|-Phe-361 site. |
| Cofactor | Binds 2 zinc ions per subunit By similarity. Binds 2 Calcium ions per subunit By similarity. |
| Subcellular location | Secreted › extracellular space › extracellular matrix By similarity. |
| Tissue specificity | Expressed specifically in the enamel organ. |
| 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 | Autoactivates at least at the 106-Asn-|-Tyr-107 site By similarity. |
| Sequence similarities | Belongs to the peptidase M10A family. Contains 4 hemopexin-like domains. |
