Cytosolic aldo-keto reductase that catalyzes the NADH and NADPH-dependent reduction of ketosteroids to hydroxysteroids (PubMed:19218247). Most probably acts as a reductase in vivo since the oxidase activity measured in vitro is inhibited by physiological concentrations of NADPH (PubMed:14672942). Displays a broad positional specificity acting on positions 3, 17 and 20 of steroids and regulates the metabolism of hormones like estrogens and androgens (PubMed:10998348). Works in concert with the 5-alpha/5-beta-steroid reductases to convert steroid hormones into the 3-alpha/5-alpha and 3-alpha/5-beta-tetrahydrosteroids. Catalyzes the inactivation of the most potent androgen 5-alpha-dihydrotestosterone (5-alpha-DHT) to 5-alpha-androstane-3-alpha,17-beta-diol (3-alpha-diol) (PubMed:15929998, PubMed:17034817, PubMed:17442338, PubMed:8573067). Also specifically able to produce 17beta-hydroxy-5alpha-androstan-3-one/5alphaDHT (PubMed:10998348). May also reduce conjugated steroids such as 5alpha-dihydrotestosterone sulfate (PubMed:19218247). Displays affinity for bile acids (PubMed:8486699).

AKR1C2 also known as Aldo-keto reductase family 1 member C2 is an enzyme with a molecular mass of approximately 37 kDa. It performs an important role in the reduction of ketosteroids. This protein transforms steroids prostaglandins and other carbonyl-containing compounds into their respective alcohol products employing NADPH as a cofactor. AKR1C2 is mostly expressed in liver tissues but it is also found in the prostate mammary glands and some brain regions.
AKR1C2 is involved in drug metabolism and hormone regulation. This enzyme contributes to converting circulating hormones such as androgens and estrogens into their active forms thereby influencing hormonal balance. While not directly part of a larger protein complex AKR1C2 interacts with other enzymes within the aldo-keto reductase family which have overlapping substrates and contribute to maintaining steroid homeostasis.
Steroid metabolism and prostaglandin pathways prominently feature AKR1C2. The enzyme plays a role in the conversion of dihydrotestosterone (DHT) to a less active form impacting androgen signaling. Additionally AKR1C2 relates to the arachidonic acid pathway by modulating prostaglandin availability with interactions seen with enzymes like microsomal prostaglandin E synthase-1 (mPGES-1) showing its broader involvement in inflammatory response.
AKR1C2 connects significantly to prostate cancer and polycystic ovary syndrome (PCOS). The enzyme's activity influences androgen levels with excessive or diminished activity linked to disease progression. In prostate cancer its modulation of DHT may contribute to cancer cell proliferation often seen with other dysregulated proteins in the androgen receptor pathway. Similarly in PCOS altered AKR1C2 expression can disrupt normal hormonal balances with implications on reproductive health.
