Specifications

Our Abpromise guarantee covers the use of ab4989 in the following tested applications.

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

  • Applications

    Blocking

  • Form

    Lyophilised
  • Additional notes


    This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and furin convertase, catalog ab3467. Using a solution with equal weights per unit volume of peptide and corresponding antibody will yield a solution with a large molar excess of peptide that is able to competitively bind the antibody.

  • Function

    Furin is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/R)R consensus motif.
  • Tissue specificity

    Seems to be expressed ubiquitously.
  • Sequence similarities

    Belongs to the peptidase S8 family. Furin subfamily.
    Contains 1 homo B/P domain.
  • Domain

    Contains a cytoplasmic domain responsible for its TGN localization and recycling from the cell surface.
  • Post-translational
    modifications

    The inhibition peptide, which plays the role of an intramolecular chaperone, is autocatalytically removed in the endoplasmic reticulum (ER) and remains non-covalently bound to furin as a potent autoinhibitor. Following transport to the trans Golgi, a second cleavage within the inhibition propeptide results in propeptide dissociation and furin activation.
    Phosphorylation is required for TGN localization of the endoprotease. In vivo, exists as di-, mono- and non-phosphorylated forms.
  • Cellular localization

    Golgi apparatus > trans-Golgi network membrane. Cell membrane. Shuttles between the trans-Golgi network and the cell surface. Propeptide cleavage is a prerequisite for exit of furin molecules out of the endoplasmic reticulum (ER). A second cleavage within the propeptide occurs in the trans Golgi network (TGN), followed by the release of the propeptide and the activation of furin.
