Background

Trappin-2 is the human member of the trappin gene family that contains SLPI (1). Trappin-2 consists of an N-terminal transglutaminase substrate domain (residues 23‑60) and a C-terminal four-disulfide core or whey acidic protein (WAP) domain (residues 72‑117). Elafin or ESI (elastase-specific inhibitor) and SKALP (skin-derived anti-leucoproteinase) 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, which can be isolated naturally. The recombinant human Trappin-2 corresponds to the full‑length form (residues 23‑117), which migrates as two protein bands under SDS-PAGE due to an unidentified mechanism. In addition to its ability to inhibit human neutrophil elastase, it can also be used as a substrate for transglutaminases.
