Regulation of asparagine synthetase gene transcription by the basic region leucine zipper transcription factors ATF5 and CHOP
1 Jan 2005
Abstract excerpt
Asparagine synthetase catalyses the glutamine- and ATP-dependent conversion of aspartic acid to asparagine. In human hepatoma cells cultured in medium containing amino acids, the mRNA of asparagine synthetase is not detectable by RNase protection mapping. However, maintaining the cells in amino acid-free Krebs-Ringer bicarbonate buffer strongly upregulated asparagine synthetase biosynthesis. The effect of amino...
