  • Product overview

    Abcam MMP12 Inhibitor Screening Assay Kit (Fluorometric) (ab139442) Kit is a complete assay system designed to screen MMP12 inhibitors using a quenched fluorogenic peptide: MMP Fluorogenic Substrate Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH2 [Mca = (7-methoxycoumarin-4-yl)-acetyl; Dpa=N-3-(2,4-dinitrophenyl)-L-α-ß-diaminopropionyl]. Mca fluorescence is quenched by the Dpa group until cleavage by MMPs at the Gly-Leu bond separates the two moieties. The assays are performed in a convenient 96-well microplate format.

  • Notes

    The kit is useful to screen inhibitors of MMP12, a potential therapeutic target. The compound NNGH is also included as a prototypic control inhibitor.

  • 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.
