MPO
A gene on chromosome 17q23.1 that encodes myeloperoxidase during myeloid differentiation. MPO is the major component of neutrophil azurophilic granules and produces hypohalous acids (e.g., hypochlorous acid) and other toxic intermediates central to the microbicidal activity of netrophils.Segen's Medical Dictionary. © 2012 Farlex, Inc.
