  • Function

    Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form.
  • Sequence similarities

    Belongs to the intercrine alpha (chemokine CxC) family.
  • Post-translational

    Binds non-covalently to a proteoglycan molecule.
  • Cellular localization
