Previous GeneCards Identifiers for MPO Gene
Myeloperoxidase (MPO) is a heme protein synthesized during myeloid differentiation that constitutes the major component of neutrophil azurophilic granules. Produced as a single chain precursor, myeloperoxidase is subsequently cleaved into a light and heavy chain. The mature myeloperoxidase is a tetramer composed of 2 light chains and 2 heavy chains. This enzyme produces hypohalous acids central to the microbicidal activity of neutrophils. [provided by RefSeq, Nov 2014]
GeneCards Summary for MPO Gene
MPO (Myeloperoxidase) is a Protein Coding gene. Diseases associated with MPO include myeloperoxidase deficiency and vasculitis. Among its related pathways are amb2 Integrin signaling and Transcriptional misregulation in cancer. GO annotations related to this gene include chromatin binding and heme binding. An important paralog of this gene is EPX.
UniProtKB/Swiss-Prot for MPO Gene
Part of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity
