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.
ScerGAL4NP5103 drives expression in three uniglomerular antennal lobe projection neurons. Two cell bodies are positioned in the anterior-dorsal part of the antennal lobe and they project to antennal lobe glomerulus VM2 only. One cell body is positioned in the lateral part and innervates glomerulus VP1.
Expression is observed in 2 projection neurons in antennal glomerulus VM2.
