MPO（myeloperoxidase），癌症关联基因，基因ID：4353，Myeloperoxidase（MPO）是髓系分化过程中合成的一种血红素蛋白，是嗜中性粒细胞嗜盐颗粒的主要成分。作为一个单链前体，髓过氧化物酶随后裂解成轻和重链。成熟髓过氧化物酶是由2个轻链和2个重链组成的四聚体。这种酶产生的次卤酸是中性粒细胞杀菌活性的核心。[由RefSeq提供，2014年11月]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]。
