Specifications

Our Abpromise guarantee covers the use of ab134442 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Biological activity
    The specific activity of ab134442 is >100 mU/mg when assayed with the synthetic substrate N-(2,4)-dinitrophenyl-Pro-Gln-Gly Ile-Ala-Gly-Gln-D-Arg (Dnp-petide).
  • Applications

    SDS-PAGE

    Functional Studies

  • Purity
    >90% by SDS-PAGE.

  • Form
    Liquid
  • Additional notes
    Do not dilute ab134442 for activation. The enzyme needs to be activated by trypsin (2 µl trypsin; 1mg/ml) for 10 - 20 min. at 37°C and stopped by the addition of inhibitor (10 µl trypsin-inhibitor; 2 mg/ml or aprotinin or TLCK) or activation by 2 mM (final concentration) aminophenylmercuric acetate (APMA, FW 351.8) for 60 min at 37°C.

  • Function
    Cleaves collagens of types I, II, and III at one site in the helical domain. Also cleaves collagens of types VII and X. In case of HIV infection, interacts and cleaves the secreted viral Tat protein, leading to a decrease in neuronal Tat's mediated neurotoxicity.
  • Sequence similarities
    Belongs to the peptidase M10A family.
    Contains 4 hemopexin-like domains.
  • Domain
    There are two distinct domains in this protein; the catalytic N-terminal, and the C-terminal which is involved in substrate specificity and in binding TIMP (tissue inhibitor of metalloproteinases).
    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
    modifications
    Undergoes autolytic cleavage to two major forms (22 kDa and 27 kDa). A minor form (25 kDa) is the glycosylated form of the 22 kDa form. The 27 kDa form has no activity while the 22/25 kDa form can act as activator for collagenase.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix.
  • Information by UniProt
