NADPH oxidase, EF-hand calcium binding domain 5, also known as NOX5, is a protein which in humans is encoded by the NOX5 gene.^[1][2]

Function

NOX5 is a novel NADPH oxidase that generates superoxide.^[1]

Nox5 interacts with c-abl, superoxide production leads to phosphorylation of c-abl, while inhibition of c-abl kinase activity inhibits Nox5 superoxide production.^[3]
