Eosinophil peroxidase (UniProt: P11678; also known as EC:1.11.1.7, EPO, EPX) is encoded by the EPX (also known as EPER, EPO, EPP) gene (Gene ID: 8288) in human. Eosinophil peroxidase is an enzyme found in cytoplasmic granules of eosinophils. It mediates tyrosine nitration of secondary granule proteins in mature resting eosinophils. It is synthesized with a signal peptide (aa 1-17) and a propeptide (aa 18-139), which are subsequently cleaved off to produce the mature form that can be cleaved into a light chain (aa 140-250) and a heavy chain (aa 251-715). These chains can assemble to for a tetrameric structure. It is a heme-containing enzyme that physically associates with fibrous tissue and cancer tissue in various organs. It contains well-conserved profibrogenic capacity to stimulate the migration of fibroblastic cells and promote their ability to secrete collagenous proteins to generate a functional extracellular matrix (ECM) both in vitro and in vivo. It plays a role in regulating the recruitment of fibroblast and the biosynthesis of collagen ECM at sites of normal tissue repair and fibrosis. It is a key participant in generation of reactive oxidants and diffusible radical species by the phagocytes. It serves as a potent toxin towards invading parasites and the surrounding tissues. It also displays significant inhibitory activity towards Mycobacterium tuberculosis H37Rv by inducing bacterial fragmentation and lysis. (Ref.: DeNichilo, MO., et al. (2015). Am. J.
