SIGNIFICANCE: that is generated inside cells. CRITICAL ISSUES: The overall prevalence and importance of Prx-based redox signaling relays are still unknown. The same is true for alternative mechanisms of redox signaling. FUTURE DIRECTIONS: signaling. Many questions relating to Prx-based redox relays remain to be answered, including their mechanism, structural organization, and the potential role of adaptor proteins. Antioxid.
