Aflatoxin B1 aldehyde reductase member 2 (AKR7A2)

Catalyzes the NADPH-dependent reduction of succinic semialdehyde to gamma-hydroxybutyrate. May have an important role in creating the neuromodulator gamma-hydroxybutyrate (GHB).

Has wide substrate specificity. Can reduce 1,2-naphthoquinone and 9,10-phenanthrenequinone (in vitro).
