  • FunctionMay play 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 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.
  • Tissue specificityProduced by normal alveolar macrophages and granulocytes.
  • Involvement in diseaseIntervertebral disc disease
    Metaphyseal anadysplasia 2
  • Sequence similaritiesBelongs to the peptidase M10A family.
    Contains 3 fibronectin type-II domains.
    Contains 4 hemopexin repeats.
  • 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
    Processing of the precursor yields different active forms of 64, 67 and 82 kDa. Sequentially processing by MMP3 yields the 82 kDa matrix metalloproteinase-9.
    N- and O-glycosylated.
  • Cellular localizationSecreted, extracellular space, extracellular matrix.
  • Information by UniProt

The H-MMP-9 is a mixture of latent and active enzyme. On the average, about 25% of ab39308 was active. The concentration was lot dependent, and listed on the labels. The molecular weight of human MMP-9 is 92 kDa, so it should be easy to figure out the...

Thank you very much for your interest in ab39308.

Although this product can be used for this application, we have not directly tested it, therefore, I can offer a discount off a future purchase if you buy ab39308 now, test it in gelatin gel ...

MMP-9 has a propeptide domain that is cleaved just after the "Cysteine switch" region, releasing the first 100 residues.
The full length protein is 707 amino acids, with a predicted mass of 78.4 kDa, but glycosylation makes the 78 kDa protein

Thank you for contacting Abcam.

The ab39308 protein is largely in the zymogen form. The enzyme does not need to be activated before running on an SDS PAGE substrate gel (gelatin zymogram), as the SDS acts to activate some of the MMP-9.
