Enzymatic characterization and interspecies difference of phenol sulfotransferases, ST1A forms.
Cytosolic sulfotransferases, which mediate activation and detoxification of both endogenous and exogenous compounds, consist of at least five different gene families (ST1 to ST5) in mammals. Several cDNAs corresponding to ST1A forms have been reported, but their functional properties are not well characterized. In addition, only a single form of ST1A sulfotransferase has been reported in each e...
متن کاملPhenol sulfotransferases: hormonal regulation, polymorphism, and age of onset of breast cancer.
In recent years, significant effort has been made to identify genes that influence breast cancer risk. Because the high-penetrance breast cancer susceptibility genes BRCA1 and 2 play a role only in a small fraction of breast cancer cases, understanding the genetic risk of the majority of breast cancers will require the identification and analysis of several lower penetrance genes. The estrogen-...
متن کاملCytosolic sulfotransferases.
Sulfoconjugation (Sulfation or Sulfonation) is an important reaction in the phase II biotransformation of a wide number of endogenous and foreign chemicals, including: drugs, toxic chemicals, hormones, and neurotransmitters. The reaction is catalyzed by the members of the cytosolic sulfotransferase (SULT) superfamily, consisting of ten functional genes in humans. Sulfation reaction in living ce...
متن کاملCharacterization of human iodothyronine sulfotransferases.
Sulfation is an important pathway of thyroid hormone metabolism that facilitates the degradation of the hormone by the type I iodothyronine deiodinase, but little is known about which human sulfotransferase isoenzymes are involved. We have investigated the sulfation of the prohormone T4, the active hormone T3, and the metabolites rT3 and 3,3'-diiodothyronine (3,3'-T2) by human liver and kidney ...
متن کاملCharacterization of rat iodothyronine sulfotransferases.
Sulfation appears to be an important pathway for the reversible inactivation of thyroid hormone during fetal development. The rat is an often used animal model to study the regulation of fetal thyroid hormone status. The present study was done to determine which sulfotransferases (SULTs) are important for iodothyronine sulfation in the rat, using radioactive T4, T3, rT3, and 3,3'-T2 as substrat...
