MPO / Myeloperoxidase

myeloperoxidase

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 (12 kD) and 2 heavy chains (60 kD). This enzyme produces hypohalous acids central to the microbicidal activity of neutrophils. It is released in a degranulation process in response to bursts of oxygen consumption, which also forms H2O2. MPO and H2O2 form a complex that oxidases a large variety of substances some of which have microbicidal effects. The gene for MPO is translocated in patients with acute promyelocytic leukemia and is mutated in hereditary MPO deficiency.

Gene Name: myeloperoxidase
Synonyms: MPO, Myeloperoxidase precursor, Myeloperoxidase
Target Sequences: NM_000250 NP_000241.1 P05164
