Enables heme binding activity; identical protein binding activity; and peroxiredoxin activity. Involved in response to oxidative stress. Located in several cellular components, including euchromatin; mitochondrial matrix; and peroxisomal matrix. Human ortholog(s) of this gene implicated in methylmalonic aciduria and homocystinuria type cblC. Orthologous to human PRDX1 (peroxiredoxin 1). [provided by Alliance of Genome Resources, Apr 2022]
