Summary
Enables thioredoxin-dependent peroxiredoxin activity. Involved in several processes, including cell redox homeostasis; determination of adult lifespan; and hydrogen peroxide catabolic process. Located in mitochondrion. Is expressed in adult head; adult heart; adult thorax; and organism. Used to study autosomal recessive spinocerebellar ataxia 32. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 32. Orthologous to human PRDX3 (peroxiredoxin 3). [provided by Alliance of Genome Resources, Jan 2025]
