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.
Approximately 7 fan-shaped F1 somata are labelled with ScerGAL4NP6561. Neurites from these cells converge into a bundle that runs dorsally and the posteriorly into the fan-shaped body.
Location 3L:17014770-17014771 refined by FlyBase alignment of dbGSS accession AG219015 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation revised.
