Summary: This gene encodes a member of the peroxidase superfamily of enzymes that is produced by eosinophils and plays a critical role in eliminating tissue-invasive parasites. The encoded preproprotein undergoes proteolytic processing to generate a heterodimeric enzyme that forms a predominant component of the intracellular granules of eosinophils. Mice lacking the encoded protein exhibit resistance to ulcerative colitis induced by dextran sulfate. [provided by RefSeq, Jul 2016]

Eosinophil peroxidase contributes to renal fibrosis in the murine unilateral ureteral obstruction model.
Title: Peroxidasin and eosinophil peroxidase, but not myeloperoxidase, contribute to renal fibrosis in the murine unilateral ureteral obstruction model.
the EPX gene deletion had no impact on eosinophil-mediated clearance of gram-negative Haemophilus influenzae from the airways.
Title: Impact of eosinophil-peroxidase (EPX) deficiency on eosinophil structure and function in mouse airways.
The expression of MBP-1 and EPX was also required for induced lung expression of IL-4/IL-13 in each setting and, in turn, the induced pulmonary remodeling events and lung dysfunction.
Title: Frontline Science: Eosinophil-deficient MBP-1 and EPX double-knockout mice link pulmonary remodeling and airway dysfunction with type 2 inflammation.
EPO-mediated protein carbamylation is promoted during allergen-induced asthma exacerbation, and can both modulate immune responses and trigger a cascade of many of the inflammatory signals present in asthma.
Title: Eosinophil Peroxidase Catalyzed Protein Carbamylation Participates in Asthma.
The absence of MBP-1 and EPX promoted a concomitant loss of eosinophil lineage-committed progenitors in the marrow, identifying a specific blockade in eosinophilopoiesis as the causative event.
Title: Expression of the secondary granule proteins major basic protein 1 (MBP-1) and eosinophil peroxidase (EPX) is required for eosinophilopoiesis in mice.
HER2 was identified as a novel mediator of eosinophil peroxidase signaling. Eosinophil peroxidase, at noncytotoxic levels, can drive cell-cycle progression and proliferation.

Title: Post-translational tyrosine nitration of eosinophil granule toxins mediated by eosinophil peroxidase.
Host protection against Brugia pahangi infections was unimpaired in mice deficient in eosinophil peroxidase.
Title: Eosinophils, but not eosinophil peroxidase or major basic protein, are important for host protection in experimental Brugia pahangi infection.
Mice deficient for either eosinophil peroxidase or major basic protein on the 129/SvJ background developed significantly higher worm burdens than wild-type mice.
Title: Lack of eosinophil peroxidase or major basic protein impairs defense against murine filarial infection.
The activities of EPO, an eosinophilic secondary granule protein, do not affect the development of allergic pulmonary pathologies in the mouse lung at levels comparable to those observed in humans with asthma.
Title: Extensive eosinophil degranulation and peroxidase-mediated oxidation of airway proteins do not occur in a mouse ovalbumin-challenge model of pulmonary inflammation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
