Myeloperoxidase (MPO), an enzyme active against bacterial and fungal infections, is expressed specifically in myeloblasts and promyelocytes and minimal in other cell types. We recently identified and partially characterized an upstream enhancer located between -4100 and -3844 bp of the MPO gene. We showed that an AML1 site contributes to enhancer activity and specificity. We now demonstrate three additional footprints within the MPO enhancer and provide evidence that C/EBP and c-Myb sites contribute to its functional, tissue-specific activity. This distal enhancer appears to play an important role in the control of MPO transcription during differentiation of myeloid cells.
