Nox4, in contrast to other Nox proteins, produces large amounts of hydrogen peroxide constitutively. Known cytosolic oxidase proteins or the GTPase Rac are not required for this activity. Nox4 associates with the protein p22phox on internal membranes, where ROS generation occurs. Knockdown and gene transfection studies confirmed that Nox4 requires p22phox for ROS generation

NAD(P)H oxidase 4 mediates transforming growth factor-beta1-induced differentiation of cardiac fibroblasts into myofibroblasts.
On stimulation with TGF-beta1, Nox4 mRNA is dramatically upregulated.
