Target Data

Function Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of estradiol and estrone. May play a role in the regulation of estrogen receptor activity by metabolizing free estradiol. Maximally sulfates beta-estradiol and estrone at concentrations of 20 nM. Also sulfates dehydroepiandrosterone, pregnenolone, ethinylestradiol, equalenin, diethylstilbesterol and 1-naphthol, at significantly higher concentrations; however, cortisol, testosterone and dopamine are not sulfated.

  3. Resveratrol and all its derivatives reduced also SULT1E1 mRNA transcript level. The reduced expression of AhR, CYP1A1, and 1B1 was also found as a result of treatment with these compounds. PMID: 27854074

  8. Data suggest that the substrate specificities of SULT1E1 and SULT1A1*1 include metabolites of tamoxifen (endoxifen, 4-hydroxytamoxifen, and N-desmethyltamoxifen); these metabolites are weak inhibitors of sulfation of estradiol by SULT1E1/SULT1A1*1. PMID: 25819444

  10. Data indicate that protein-ligand interaction energy by using docking Quantitative Structure-Activity Relationships(QSAR) models showed accuracy of 67.28%, 78.00% and 75.46%, for the isoforms SULT1A1, SULT1A3 and SULT1E1, respectively. PMID: 24039991

  14. Decrease or deletion of EST in the mammary gland may be related to the development of hypertrophic breast, especially gland-associated hypertrophic breast. PMID: 21548389
  15. study showed expression patterns of SULT1E1 and PAPSS in breast and endometrial tissues; the estrogen sulfation enzymes were comparatively higher in the tumorous tissues than adjacent normal tissues; overexpression of SULT1E1 and PAPSS1 retarded MCF-7 cells growth in vivo and in vitro by arresting cell cycles and inducing apoptosis PMID: 22380844
  16. Using two iterative rounds of evolution, we generated SULT1E1 mutants with increased thermostability. PMID: 22197379
  17. results demonstrate that SULT1E1 expression in MCF10A breast epithelial cells cells is transcriptionally regulated by confluence through a suppressive action of the AhR, which is not mediated through a dioxin response element at nt -3476 PMID: 21828262
  18. Identification of the upstream enhancer of the SULT1E1 promoter that plays a crucial role in regulating the activity of SULT1E1 transcription. PMID: 21764778

  20. estrogen sulfotransferase is expressed in abdominal sc adipose tissue of both obese males and females in association with expression of TNF-alpha and SOCS3, suggesting potential roles in inflammation. PMID: 21543429
  21. Human EST (a dimer of identical protomers) presents a clear example of half-sites reactivity--only one subunit of the dimer produces product during the catalytic cycle. It is the first example of half-sites reactivity in the sulfotransferase family. PMID: 20429582

  25. Levels of steroid sulfatase and STS mRNA and activity may be significantly associated with degree of atherosclerotic changes in female aorta, which may be related to cytokines produced in situ, such as IL-1beta, in human atherosclerotic lesions. PMID: 14507642
  26. estrogen-dependent cell growth of the EST-transfected cell clones was found to be abolished, due to the enhanced sulfoconjugation of estrogen PMID: 14556660
