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.

Drives expression in neurons of the adult mushroom body gamma-lobe, and in ring neurons R4d.
ScerGAL4NP1131 drives expression in about 5 ring neurons R4d at 7-8 days of age. Labeled neurons co-express ScerGAL80ChAT.7.4P.
Labels a set of 25 embryonic-born gamma neurons on the surface layer of the third instar larvae mushroom body and is already visible at the first instar larval stage.
