Recombinant Human AKR1D1 protein
Recombinant AKR1D1 protein was expressed in E.coli and purified by using conventional chromatography techniques.
AKR1D1 also known as 3-oxo-5beta-steroid 4-deghydrogenase isoform 1, is a member of the AKR superfamily. The AKR family of proteins are soluble NADPH oxidoreductases. They play important roles in the metabolism of drugs, carcinogens and reactive aldehydes. AKR1D1 is responsible for the catalysis of the 5-betareduction of bile acid intermediates and steroid hormones which carry a delta (4)-3-one structure. AKR1D1 is highly expressed in liver, colon and testis. Deficiency of this enzyme may contribute to hepatic dysfunction.
