AKR1C1, a member of the AKR1 family.

Aldo-keto reductase family 1 (AKR1) is a family of aldo-keto reductase enzymes that is involved in steroid metabolism. It includes the AKR1C and AKR1D subgroups, which respectively consist of AKR1C1AKR1C4 and AKR1D1. Together with short-chain dehydrogenase/reductases (SDRs), these enzymes catalyze oxidoreductions, act on the C3, C5, C11, C17 and C20 positions of steroids, and function as 3α-HSDTooltip 3α-Hydroxysteroid dehydrogenases, 3β-HSDsTooltip 3β-Hydroxysteroid dehydrogenases, 5β-reductases, 11β-HSDsTooltip 11β-Hydroxysteroid dehydrogenases, 17β-HSDsTooltip 17β-hydroxysteroid dehydrogenases, and 20α-HSDsTooltip 20α-Hydroxysteroid dehydrogenases, respectively. The AKR1C enzymes act as 3-, 17- and 20-ketosteroid reductases, while AKR1D1 acts as the sole 5β-reductase in humans.
