AKR1D1 (aldo-keto reductase family 1 member D1), also known as Δ(4)-3-oxosteroid 5-β-reductase (3o5bred) or steroid 5-β-reductase (SRD5B1), is responsible for catalyzing bile acid intermediates and steroid hormones possessing a Δ(4)-3-one structure to 5-β reduced metabolites. The AKR family of proteins are soluble NADPH oxidoreductases. They play important roles in the metabolism of drugs, carcinogens and reactive aldehydes. AKR1D1 is highly expressed in liver, colon and testis. Substrates for AKR1D1 include testosterone, androstenedione, progesterone, 17-α-hydroxyprogesterone and the bile acid intermediates 7-α-hydroxy-4-cholesten-3-one and 7-α, 12-α-dihydroxy-4-cholesten-3-one. A deficiency in AKR1D1 may be involved in hepatic dysfunction.
