COMMENTARY
LITERATURE
malfunction
-
knock-down of SULT2B1b inhibits cell growth and cyclinB1 levels in human hepatocarcinoma cells and suppressed xenograft growth in vivo
metabolism
-
isoform SULT2B1b and its enzymatic by-product cholesterol sulfate are important metabolic regulators that control glucose metabolism. Mechanistically, cholesterol sulfate and SULT2B1b inhibit gluconeogenesis by suppressing the expression of acetyl coenzyme A synthetase, leading to decreased acetylation and nuclear exclusion of hepatocyte nuclear factor 4alpha.
physiological function
physiological function
-
SULT2B1b expression promotes proliferation of hepatocellular carcinoma cells in vitro and in vivo, which may contribute to the progression of hepatocellular carcinoma
physiological function
-
upregulation of SULT2B1b promotes hepatic oval cell proliferation and aggravate liver injury via the suppression of oxysterol-induced LXR activation in chemically induced mouse liver injury
physiological function
isoform SOT12 is required for detoxification of cycloheximide

the sulfation, catalyzed by SULT, is important in the regulation of biological activities of hormones and neurotransmitters, the metabolism of drugs, and the detoxification of xenobiotic toxicants. Sulfation also leads to the bioactivation of procarcinogens.

additional information
-
a unique 3'-extension of SULT2B1b is required for nuclear localization in human BeWo placental choriocarcinoma cells, the nuclear localization is stimulated by forskolin treatment in BeWo cells and serine phosphorylation in the 3'-extension
