Aldo-keto reductase family 1 member C4 �or AKR1C4 is a part of the aldo/keto reductase superfamily that has more then 40 known proteins & enzymes. AKR1C4 catalyzes the conversion of aldehydes and ketones to their corresponding alcohols with NADH and/or NADPH as cofactors. AKR1C4 takes place in the bioreduction of chlordecone, a toxic organochlorine pesticide, to chlordecone alcohol in the liver tissue.

AKR1C4 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 323 amino acids (1-323aa ) and having a molecular mass of �37kDa.

UniProt Protein Function:AKR1C4: Catalyzes the transformation of the potent androgen dihydrotestosterone (DHT) into the less active form, 5-alpha- androstan-3-alpha,17-beta-diol (3-alpha-diol). Also has some 20- alpha-hydroxysteroid dehydrogenase activity. The biotransformation of the pesticide chlordecone (kepone) to its corresponding alcohol leads to increased biliary excretion of the pesticide and concomitant reduction of its neurotoxicity since bile is the major excretory route. Defects in AKR1C4 are a cause of 46,XY sex reversal type 8 (SRXY8). A disorder of sex development. Affected individuals have a 46,XY karyotype but present as phenotypically normal females. AKR1C4 mutations may act as modifier of disease severity in SRXY8 patients. A splicing mutation resulting in loss of exon 2 has been found in affected individuals also carrying mutation Val-79 in AKR1C2 (PubMed:21802064). Belongs to the aldo/keto reductase family.

NCBI Summary:This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols by utilizing NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme catalyzes the bioreduction of chlordecone, a toxic organochlorine pesticide, to chlordecone alcohol in liver. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14. [provided by RefSeq, Jul 2008]
