Metabolite Identification

Common Name

Estriol

Description

Estriol is a metabolite of estrone metabolized via 16alpha-hydroxyestrone through the enzyme 16alpha-hydroxysteroid dehydrogenase (EC 1.1.1.147) or to 2- or 4-hydroxyestrone (catechol estrogens) by the action of catecho-O-methyltransferase (EC 2.1.1.6). The latter metabolites can be formed in the brain and may compete with receptors for catecholamines. Metabolites are conjugated with sulfate or glucuronide before excretion by the kidney. During pregnancy, estriol constitutes 60-70% of the total estrogens, increasing to 300-500-fold in relation to non-pregnant women. The late term human fetus produces relatively large amounts of 16 alphahydroxy DHEA, which serves the mother as a precursor of estriol. It has been shown that 90% of the precursors for the formation of estriol are of fetal origin. If abnormal maternal serum screening results, specifically low levels of unconjugated estriol in the second trimester are detected, a diagnosis of Smith-Lemli-Opitz syndrome (SLOS),or RSH is suspected. SLOS is an autosomal recessive disorder caused by mutations of the gene encoding 7-dehydrocholesterol reductase (EC 1.3.1.21, DHCR7). (PMID: 16202579 , 16112271 , 16097001 ).

Enzyme Details

2. UDP-glucuronosyltransferase 2B28

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGTs are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isozyme has glucuronidating capacity with steroid substrates such as 5-beta-androstane 3-alpha,17-beta-diol, estradiol, ADT, eugenol and bile acids. Only isoform 1 seems to be active.

3. Estrogen receptor beta

General function:: Involved in sequence-specific DNA binding transcription factor activity
Specific function:: Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform beta-cx lacks ligand binding ability and has no or only very low ere binding activity resulting in the loss of ligand-dependent transactivation ability. DNA- binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual
Gene Name:: ESR2
Uniprot ID:: Q92731
Molecular weight:: 59215.8
