PO-2 57-60 NADPH oxidase 4 Homo sapiens 130-145 25062272-8 2014 This allows Nox4 to generate H2O2 as a function of oxygen concentration throughout a physiological range of pO2 values and to respond rapidly to changes in pO2. PO-2 108-111 NADPH oxidase 4 Homo sapiens 12-16 25062272-8 2014 This allows Nox4 to generate H2O2 as a function of oxygen concentration throughout a physiological range of pO2 values and to respond rapidly to changes in pO2. PO-2 156-159 NADPH oxidase 4 Homo sapiens 12-16 23798702-5 2013 Eight additional Cys residues are oxidized at high versus low pO2 only when NADPH levels are supplemented to enhance NADPH oxidase 4 activity. PO-2 62-65 NADPH oxidase 4 Homo sapiens 117-132 21896730-3 2011 Reactive oxygen species are generated in proportion to pO(2) by NADPH oxidase 4 (Nox4) in the sarcoplasmic reticulum, and the consequent oxidation of a small set of RyR1 cysteine thiols results in increased RyR1 activity and Ca(2+) release in isolated sarcoplasmic reticulum and in cultured myofibers and enhanced contractility of intact muscle. PO-2 55-60 NADPH oxidase 4 Homo sapiens 64-79 21896730-3 2011 Reactive oxygen species are generated in proportion to pO(2) by NADPH oxidase 4 (Nox4) in the sarcoplasmic reticulum, and the consequent oxidation of a small set of RyR1 cysteine thiols results in increased RyR1 activity and Ca(2+) release in isolated sarcoplasmic reticulum and in cultured myofibers and enhanced contractility of intact muscle. PO-2 55-60 NADPH oxidase 4 Homo sapiens 81-85
