Protein Information
Name SULT1A1
Synonyms STP, STP1
Function Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of catecholamines, phenolic drugs and neurotransmitters. Has also estrogen sulfotransferase activity. responsible for the sulfonation and activation of minoxidil. Is Mediates the metabolic activation of carcinogenic N- hydroxyarylamines to DNA binding products and could so participate as modulating factor of cancer risk.

Sulphation is a significant detoxification pathway for diverse xenobiotics, yet this modification also plays an important role in the metabolism and bioactivation of many dietary and environmental mutagens, including heterocyclic amines implicated in the pathogenesis of several cancers. A major human sulfotransferase, SULT1A1, metabolizes and/or bioactivates many endogenous compounds and is implicated in a range of cancers because of its ability to transform xenobiotics to cellular mutagens and carcinogens. Genetic polymorphisms in human sulfotransferase 1A1 SULT1A1 have a major impact on SULT1A1 enzyme activity and affect the risk for cancer development in humans. A G--->A transition at codon 213 (CGC/Arg to CAC/His) of the SULT1A1 gene has been identified (SULT1A1*2), and individuals homozygous for the His allele have a markedly lower activity and stability of this enzyme than those with the high activity SULT1A1*1 allozyme, which has been associated with protection against dietary toxins and reduced susceptibility to colorectal and breast cancers.There is an increasing incidence of SULT1A1*1 homozygosity and decreasing incidence of SULT1A1*2 homozygosity with increasing age, indicating a potential association of SULT1A1*1 allozyme(s) with protection against cell and/or tissue damage during aging. CLN3, the locus for Batten disease, maps to the same region 16p12.1-p11.2 as SULT12A1, making SULT1A1 a candidate gene for this disorder.
