Here, the authors demonstrate that altering the epistatic interaction between Gal80p and Gal4p also abolishes the bistability of the GAL/MEL genetic switch, and the switch response to galactose becomes graded instead of binary.
Title: The binary response of the GAL/MEL genetic switch of Saccharomyces cerevisiae is critically dependent on Gal80p-Gal4p interaction.
To facilitate application of the KZip(+) technology, we have developed a versatile set of LexAop-KZip(+) fly lines that can be used directly with the large number of LexA driver lines with known expression patterns. KZip(+) significantly sharpens the precision of neuronal genetic control available in Drosophila and may be extended to other organisms where Split GAL4-like systems are used.
