… Nuclear levels of the antioxidant enzyme Peroxiredoxin 2 (PRDX2) were found to
oscillate rhythmically over two entire 24 h long cycles. Donwregulation of PRDX2 resulted in …

… clock, and its depletion leads to ablation of biological rhythm [6,7]. The master circadian
clock is … Prdx 1 to 5 contains 2-Cys Prdx, while Prdx6 has a single conserved Cys. Prdx6 is …

… the circadian rhythm of H 2 O 2 release. … –SO 2 H) is reduced and reactivated by sulfiredoxin
(Srx). We also found that the amounts of PrxIII–SO 2 H and Srx undergo antiphasic circadian …

… Here we show that oxidation–reduction cycles of peroxiredoxin proteins constitute a universal
marker for circadian rhythms in all domains of life, by characterizing their oscillations in a …

… -Cys PRDXs has been seem as an evolutionary adapted mechanisms to allow H 2 O 2 -dependent
cell signaling purposes, circadian rhythm to PRDXs recycling/function and …

… , circadian rhythms in these cells testify to the existence of a nontranscriptional circadian
clock… The catalytic cysteine of peroxiredoxin (PRX) can be oxidized to a sulfenic acid form (PRX-…

… By trial and error, we found that the circadian rhythm of Prx hyperoxidation could be monitored
for 48 h by maintenance of mouse RBCs in a modified version of DMEM. Experimental …
