Dual oxidase

Gene

Duox

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Plays a role in innate immunity limiting microbial proliferation in the gut (PubMed:16272120, PubMed:25639794). Acts downstream of a hh-signaling pathway to induce the production of reactive oxygen species (ROS) in response to intestinal bacterial infection (PubMed:25639794). May generate antimicrobial oxidative burst through its peroxidase-like domain (PubMed:16272120).2 Publications

Catalytic activityi

NAD(P)H + O2 = NAD(P)+ + H2O2.1 Publication

Enzyme regulationi

Peroxidase activity is inhibited by aminotriazole and azide.1 Publication
