The function of ENSG00000162482 (AKR7A3, aldo-keto reductase family 7 member A3) is as follows. Catalyzes the NADPH-dependent reduction of various carbonyl- containing compounds, including aldehydes, ketones, and toxic products from cellular metabolism or environmental exposure. Can reduce the dialdehyde form of aflatoxin B1 (AFB1) into alcohol derivatives, via monoaldehydes intermediates. Can reduce the dialdehyde form of aflatoxin B1 (AFB1) into alcohol derivatives, via monoaldehydes intermediates, thus preventing the formation of protein adducts that contribute to AFB1-induced toxicity. {ECO:0000269|PubMed:10383892, ECO:0000269|PubMed:11409944, ECO:0000269|PubMed:18416522}.
