  • protease inhibitor 3, skin-derived (SKALP)
  • Protease inhibitor WAP3
  • Skin-derived antileukoproteinase
  • Trappin2

  • WFDC14elafin


Trappin-2 is a member of the trappin family that includes the SLPI (secretory leukocyte protease inhibitor) protein. Elafin or ESI (elastase-specific inhibitor) and SKALP (skin-derived anti-leukoproteinase) are alternative names for trappin-2 and reflect its protease targets. However, Elafin and SKALP sometimes correspond only to the processed form that contains the C-terminal WAP domain of the molecule.
