Predicted to enable glyoxylate reductase (NADPH) activity and hydroxypyruvate reductase (NADH) activity. Predicted to be active in cytosol. Is expressed in hypural; liver; pronephric duct; pronephros; and yolk syncytial layer. Human ortholog(s) of this gene implicated in primary hyperoxaluria and primary hyperoxaluria type 2. Orthologous to human GRHPR (glyoxylate and hydroxypyruvate reductase).
