NADPH oxidase complexes are multiprotein assemblies that generate reactive oxygen species in a variety of mammalian tissues. The canonical phagocytic oxidase consists of a heterodimeric, enzymatic core comprised of the transmembrane proteins, CYBB andCYBA and is regulated, in part, by an "organizing" function of NCF1 and an "activating" activity of NCF2. In contexts outside of the phagocyte, these regulatory functions may be encoded not only by NCF1 and NCF2, but also alternatively by their respective paralogues, NOXO1 and NOXA1. To allow tissue-specific dissection of Noxa1 function in mouse, we have generated an allele of Noxa1 suitable for conditional inactivation. Moreover, by crossing Noxa1 conditional allele carriers to B6.129S4-Meox2(tm1(Cre)Sor)/J mice, we have generated first, Noxa1-null heterozygotes, and ultimately, Noxa1-null homozygotes. Through the thoughtful use of tissue-specific, Cre-expressing mouse strains, the Noxa1 conditional allele will offer insight into the roles of NOXA1 in the variety of tissues in which it is expressed.
