A set of transgenic insertion stocks derived by TE mobilization using the P-element construct P{GawB}. The P{GawB} construct carries a w+mW.hs mini-white visible marker and Scer\GAL4 driver/enhancer trap sequences. The GAL4-UAS system is a binary system using Scer\GAL4, a yeast transcription activator protein gene, and Scer\UAS, the DNA binding site for the GAL4 protein. The P{GawB} construct acts as an enhancer trap: expression of the GAL4 is sensitive to enhancers in the genomic region of an insertion. When paired with a construct or insertion carrying a reporter gene downstream of Scer\UAS, the reporter gene is driven by and reflects the expression of the GAL4.
ScerGAL4NP0881 drives expression in around 17 uniglomerular antennal lobe projection neurons. The cell bodies of around 12 of these neurons are positioned in the anterior-dorsal part of the antennal lobe and around 5 cell bodies are found in the lateral part. These neurons project to 8 different antennal lobe glomeruli.
Location 3R:18356305-18356306 refined by FlyBase alignment of dbGSS accession AG218465 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation revised.
