AKR1C1 monoclonal antibody

Human liver contains isoforms of dihydrodiol dehydrogenase (DD1, DD2, DD3 and DD4), which belong to the aldo-oxo reductase / aldo-keto reductase (AKR) superfamily, have 20α- or 3α-hydroxysteroid dehydrogenase AKD1C3 and 3α-HSD are alternate designations for human DD3 (which is referred to as AKR1C18 in rodents), while DD4 is also designated as AKR1C1, DDH or DDH1, while DD2 also can be designated AKR1C2, dDD, BABP or DDH2. AKR1C4, CD, CHDR or AKR1C6 (in rodents). DD1 and DD2 are 20α-HSDs, DD3 and DD4 are the 3α-HSDs. The 20α-HSD catalyzes the reaction of progesterone to the inactive form 20α-hydroxyprogesterone. The 3α-HSD is a cytosolic, monomeric, NADPH-depen DD1 and DD2 are ubiquitously expressed, whereas DD4 mRNA is restricted to the liver. DD3 is a unique enzyme that can specifically catalyze the dehydrogenation of trans-benzene dihydrodiol and trans- naphthalenedihydrodiol.
