WebOne particular tool is the GAL4/UAS system that allows for the expression of genes from any organism in a tissue and temporal-specific manner. This has led to the identification of conserved genes involved in apoptosis [ 1 ], tyrosine kinase signaling [ 2] and neurodegenerative diseases. GAL4 is a yeast protein that regulates genes induced by ... WebThe system makes use of the transcriptional machinery required for galactose metabolism in yeast: the GAL4 protein binds to its upstream activating sequence (UAS) and activates gene expression. In Drosophila , GAL4 expression is under the control of a tissue-specific enhancer and the gene of interest is under the control of UAS.
