Elafin, also known as peptidase inhibitor 3 or skin-derived antileukoprotease (SKALP), is a protein that in humans is encoded by the PI3 gene.[3][4][5]

Function

edit

This gene encodes an elastase-specific protease inhibitor, which contains a WAP-type four-disulfide core (WFDC) domain, and is thus a member of the WFDC domain family. Most WFDC gene members are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. This gene belongs to the centromeric cluster.[5]

Clinical significance

edit

Elafin has been found to have utility in serving as a biomarker for graft versus host disease of the skin.[6]

Elafin plays some role in gut inflammation. [7]
