Project context and summary :
Nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (or NOX) are a unique family of enzymes dedicated to the production of reactive oxygen species (ROS) such as superoxide anion (O.-2) and hydrogen peroxide (H2O2) (1). This family includes NOX1-5, DUOX1 and DUOX2 and has been defined on the basis of its members’ structural homology with gp91PHOX (now renamed NOX2), the catalytic core of the phagocyte NADPH oxidase. A functional phagocytic NADPH oxidase complex consists of the membrane-anchored flavocytochrome b558 (the catalytic core of the enzyme composed of gp91PHOX and p22PHOX), the regulatory cytosolic proteins p47PHOX, p67 PHOX, p40 PHOX, and the low molecular-weight GTP-binding proteins, Rac 1 or 2 . NADPH oxidase 1 (NOX1), the first homologue of gp91PHOX identified in colon epithelial cells, is the NOX family member most closely related to phagocytic NADPH oxidase in terms of its structure and function . NOX1, NOXO1 and NOXA1 transcripts are abundantly expressed in the colon where they could be involved in mucosal innate immunity under physiological conditions . During inflammatory and infectious conditions NOXO1 is the mostly upregulated subunit [5-6].
