Metabolite Identification

Common Name

Allopregnanolone

Description

Allopregnanolone is a neuroactive metabolite of progesterone and a barbiturate-like modulator of central gamma-aminobutyric acid receptors that modify a range of behaviors, including the stress response. is a steroid created in the body when progesterone, the female sex hormone, is metabolized. Typically, THP (allopregnanolone) is released in the brain in response to stress, and quiets the neural system within 30 minutes of escalation. This steroid hormone has recently been found to be responsible for the extreme mood swings found in teenagers. In adults and pre-pubescent chlidren THP normally helps soothe the activity of brain cells by binding to GABA receptors that inhibit accelerating electrical activity. However, in pubescent teenagers THP actually becomes a GABA receptor antagonist. GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the brain with most sedatives (tranquilizers, anesthetics and alcohol) acting on the GABA receptor.

Enzymes

Enzyme Details

1. Aldo-keto reductase family 1 member C3

General function:: Involved in oxidoreductase activity
Specific function:: Catalyzes the conversion of aldehydes and ketones to alcohols. Catalyzes the reduction of prostaglandin (PG) D2, PGH2 and phenanthrenequinone (PQ) and the oxidation of 9-alpha,11-beta-PGF2 to PGD2. Functions as a bi-directional 3-alpha-, 17-beta- and 20-alpha HSD. Can interconvert active androgens, estrogens and progestins with their cognate inactive metabolites. Preferentially transforms androstenedione (4-dione) to testosterone.
Gene Name:: AKR1C3
Uniprot ID:: P42330
Molecular weight:: 36866.91

Reactions

5a-Pregnane-3,20-dione + NADPH + Hydrogen Ion → Allopregnanolone + NADP	details

Enzyme Details

2. Aldo-keto reductase family 1 member C1

General function:: Involved in oxidoreductase activity
Specific function:: Converts progesterone to its inactive form, 20-alpha-dihydroxyprogesterone (20-alpha-OHP). In the liver and intestine, may have a role in the transport of bile. May have a role in monitoring the intrahepatic bile acid concentration. Has a low bile-binding ability. May play a role in myelin formation.
Gene Name:: AKR1C1
Uniprot ID:: Q04828
Molecular weight:: 36788.02

Reactions

5a-Pregnane-3,20-dione + NADPH + Hydrogen Ion → Allopregnanolone + NADP	details

Enzyme Details

3. Aldo-keto reductase family 1 member C2

General function:: Involved in oxidoreductase activity
Specific function:: 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). Has a high bile-binding ability.
Gene Name:: AKR1C2
Uniprot ID:: P52895
Molecular weight:: 15747.91
