Biochem/physiol Actions

Inhibitor of human leukocyte elastase and proteinase 3, originally isolated from the skin of patients with psoriasis. May protect against certain autoimmune tissue damage. An elastase inhibitor which is an active fragment of elafin, as well as elafin itself, can also be found in bronchial carcinoma secretions.
Exhibits co-existent antimicrobial and antiproteolytic activities.1 Inhibits WAP-type four-disulfide core (WFDC) domain containing elastases. Antimicrobial spectrum: Gram-positive and Gram-negative bacteria.
