Application Abreviews Notes
WB 1/500 - 1/3000. Predicted molecular weight: 54 kDa.
IHC-P 1/100 - 1/1000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF 1/100 - 1/1000.


  • Function

    May be involved in tissue injury and remodeling. Has significant elastolytic activity. Can accept large and small amino acids at the P1' site, but has a preference for leucine. Aromatic or hydrophobic residues are preferred at the P1 site, with small hydrophobic residues (preferably alanine) occupying P3.
  • Tissue specificity

    Found in alveolar macrophages but not in peripheral blood monocytes.
  • Sequence similarities

    Belongs to the peptidase M10A family.
    Contains 4 hemopexin-like domains.
  • 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.
  • Cellular localization

    Secreted > extracellular space > extracellular matrix.
  • Information by UniProt
  • Database links

  • Form

    The presence of a 22kDa truncated active form of MMP-12 in vitro as well as in vivo due to the internal autolytic cleavage of the C-terminus.
