Peptidase inhibitor 3 (PI3), also known as Elafin, is a gene located on chromosome 20q13.12, encoding a protein that functions as a serine protease inhibitor. Elafin is primarily expressed in epithelial tissues, including skin and mucosal surfaces, where it plays a protective role against excessive proteolytic activity by inhibiting enzymes like neutrophil elastase and proteinase 3. This activity is crucial for maintaining tissue homeostasis and preventing inflammatory damage. PI3 is regulated by pro-inflammatory cytokines and is involved in modulating inflammatory responses and tissue repair processes. Its expression is often elevated in conditions characterized by inflammation, such as chronic obstructive pulmonary disease (COPD), psoriasis, and other inflammatory diseases, reflecting its role in guarding against protease-induced tissue damage. Research into PI3 focuses on its potential therapeutic applications in inflammatory diseases and its utility as a biomarker for assessing inflammation-related pathologies.
