产品介绍 background:
EPX, eosinophil peroxidase, is an antimycobacterial protein that localizes to cytoplasmic granules of eosinophils and recruits bromide to generate a halogenating oxidant. EPX dependent generation of hypobromous acid causes damage to tissue during inflammatory conditions that include asthma, allergies,cancer and parasitic/helminthic infections. EPX is a major enzyme present in eosinophils and upon degranulation, becomes released into the airways of asthmatics. As a result of its cationic nature and its ability to catalyze the formation of highly toxic oxidants, EPX can induce lung injury in a JNK dependent manner. 

Function:
Mediates tyrosine nitration of secondary granule proteins in mature resting eosinophils. Shows significant inhibitory activity towards Mycobacterium tuberculosis H37Rv by inducing bacterial fragmentation and lysis.

Subunit:
Tetramer of two light chains and two heavy chains.

Subcellular Location:
Cytoplasmic granule. Note=Cytoplasmic granules of eosinophils.

DISEASE:
Defects in EPX are the cause of eosinophil peroxidase deficiency (EPD) [MIM:261500]. EPD is an autosomal recessive defect where anomalous eosinophils are characterized by nuclear hypersegmentation, hypogranulation, and negative peroxidase and phospholipid staining.

Similarity:
Belongs to the peroxidase family. XPO subfamily.
