Summary: Enables thioredoxin peroxidase activity. Involved in several processes, including cellular response to hydrogen peroxide; determination of adult lifespan; and positive regulation of brood size. Located in cytoplasm. Is expressed in several structures, including intestine; nervous system; pharynx; reproductive system; and tail. Human ortholog(s) of this gene implicated in methylmalonic aciduria and homocystinuria type cblC. Orthologous to human PRDX1 (peroxiredoxin 1) and PRDX2 (peroxiredoxin 2).

Early developmental nanoplastics exposure disturbs circadian rhythms associated with stress resistance decline and modulated by DAF-16 and PRDX-2 in C. elegans.
Title: Early developmental nanoplastics exposure disturbs circadian rhythms associated with stress resistance decline and modulated by DAF-16 and PRDX-2 in C. elegans.
Analysis of the in vivo redox status demonstrated that at 25 degrees C, C. elegans larvae have a more reduced redox state and higher Prdx-2 expression levels than animals raised at 15 degrees C. Worms lacking prdx-2 fail to show the additional lifespan extension upon shift from 25 degrees C to 15 degrees C and reveal a lifespan similar to prdx-2 worms always kept at 15 degrees C.
Title: Do developmental temperatures affect redox level and lifespan in C. elegans through upregulation of peroxiredoxin?
PRDX-2 is required for insulin secretion and insulin/IGF-1-dependent regulation of stress resistance and longevity.
Title: A peroxiredoxin, PRDX-2, is required for insulin secretion and insulin/IIS-dependent regulation of stress resistance and longevity.
PRDX2 has a role in Metformin promotion of lifespan through mitohormesis
Title: Metformin promotes lifespan through mitohormesis via the peroxiredoxin PRDX-2.
While PRDX-2 acts in the intestine to protect against environmental stress, PRDX-2 in other tissues influences endogenous mechanisms that promote longevity.
Title: A redox-sensitive peroxiredoxin that is important for longevity has tissue- and stress-specific roles in stress resistance.
