Predicted to enable identical protein binding activity and thioredoxin peroxidase activity. Predicted to be involved in cell redox homeostasis; hydrogen peroxide catabolic process; and response to oxidative stress. Predicted to act upstream of or within several processes, including negative regulation of male germ cell proliferation; peptidyl-proline hydroxylation to 4-hydroxy-L-proline; and protein maturation by protein folding. Located in extracellular space and smooth endoplasmic reticulum. Orthologous to human PRDX4 (peroxiredoxin 4). [provided by Alliance of Genome Resources, Apr 2022]
