The Gal4 / UAS system as a tool for neuroscienceScott, E. K
a A diagram to show different brain regions in the adult fly (top) and the inactivation scheme by the GAL4/UAS system (bottom). Different Gal4s drove the expression of TNT in specific neurons in selected brain regions, including the mushroom body (b), ellipsoid body (c), fan-shaped body...
Advances in Drosophila genetics has enabled tissue specific knockdown of specific genes through the GAL4-UAS system. This technology has been used for the previous decade and is based on the properties of the yeast transcriptional activator Gal4 that activates transcription of its target genes by bi...
To facilitate tissue-specific analysis of Dichaete action, we generated dominant negative (DN) Dichaete proteins and expressed them in specific tissues via the GAL4-UAS system [25]. We produced three types of construct: two dominant negative proteins, either lacking the Dichaete HMG DNA-binding...

In order to assess the role of specific neurons in the modulation of larval photobehavior, we used the GAL4/UAS system [33]. In this approach, specific enhancers or promoters are used to regulate the expression of the yeast transcription factor GAL4. A gene of interest, such as tetanus to...
Besides the clonal analysis, we took advantage of the GAL4-UAS system (Brand and Perrimon 1993) to appose cells with different levels of fz expression as described previously (Adler et al. 1997) and examined how the distribution of Fmi was altered. The patched (ptc)-GAL4 driver was used ...
The reporter gene constructs (GAL4-UAS) and effector constructs (SPL4, SPL4-d3, SPL4-d15) were performed as previously described (Lyu et al.,2020). Briefly, the GAL4-UAS was cloned and inserted into the pGreenII 0800-LUC vector as the reporter. The full-length CDSs of OsSPL4, Os...
Thus, we reduced Upf2 levels specifically in the fly brain using the GAL4-upstream activating sequence (UAS) system and a conditional Upf2 RNAi construct (UAS-Upf2RNAi; STAR Methods). As expected, in the brain of Upf2RNAi flies, Upf2 levels were significantly decreased (Figure S4H), and...
We created a GAL4/UAS bigenic mouse system to overexpress BMP4 or a mutant form of BMP4 (mutBMP4), which lacks a subset of amino-terminal basic amino acids that limits its range of action, in the dorsal neural tube. UAS-Bmp4 and UAS-mutBmp4 responder genes were activated in the ...
