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.

ScerGAL4NP1579 drives expression in around 23 uniglomerular antennal lobe projection neurons. The cell bodies of around 13 of these neurons are positioned in the anterior-dorsal part of the antennal lobe. Around 8 cell bodies are found in the lateral part and around 2 are positioned ventrally. These neurons project to 8 different antennal lobe glomeruli including DA4.
