Description

DEFINITION

Aldo-keto reductase family 1 belong to 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.

Human Family 1 includes the genes:

  • AKR1C1 This enzyme catalyzes the reduction of progesterone to the inactive form 20-alpha-hydroxy-progesterone
  • AKR1C2
  • AKR1C3 Aldo-keto reductase family 1 member C3 is an enzyme that 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 reduction of prostaglandin (PG) D2, PGH2 and phenanthrenequinone (PQ), and the oxidation of 9alpha,11beta-PGF2 to PGD2. It may play an important role in the pathogenesis of allergic diseases such as asthma, and may also have a role in controlling cell growth and/or differentiation. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14
  • AKR1C4

These genes gene share high sequence identity and are clustered at chromosome 10p15-p14
