Function

function

Matrix metalloproteinase that plays an essential role in local proteolysis of the extracellular matrix and in leukocyte migration. Could play a role in bone osteoclastic resorption. Cleaves KiSS1 at a Gly-|-Leu bond. Cleaves NINJ1 to generate the Secreted ninjurin-1 form. Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

  • Cleavage of gelatin types I and V and collagen types IV and V.
    EC:3.4.24.35 (UniProtKB | ENZYME | Rhea)

Cofactor

Protein has several cofactor binding sites:
Ca2+ (UniProtKB | Rhea| CHEBI:29108 )

Note: Can bind about 5 Ca2+ ions per subunit.
Zn2+ (UniProtKB | Rhea| CHEBI:29105 )

Note: Binds 2 Zn2+ ions per subunit.
