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.
ScerGAL4nab-NP1316 drives expression in neuroblast lineages, including the Rx positive ganglion mother cell and Kenyon cell descendants of mushroom body neuroblasts.
ScerGAL4NP1316 drives expression in all larval VNC neuroblasts from embryonic stage 16.
Location 3L:4144512-4144513 refined by FlyBase alignment of dbGSS accession AG216219 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation revised.
