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.
ScerGAL4NP7088 drives expression in a pattern similar to that of ScerGAL4Tdc2.PS, labeling most of the ScerGAL4Tdc2.PS-expressing neurons in the thoracic and abdominal segments of the larval ventral nerve cord, though not those in the brain and subesophageal ganglion.
ScerGAL4NP7088 drives expression in several clusters of cells in the adult, in a total of 333 cells per hemisphere. These clusters include the octopaminergic neurons VM (34 cells) and AL2 (11 cells). In addition, ScerGAL4NP7088 labels cells in the middle inferior lateral protocerebrum (MIL cluster, 97 cells), middle superior medial protocerebrum (MSM cluster, 12 cells), posterior lateral protocerebrum (PL cluster, 19 cells), and in the lateral subesophageal ganglion (SOG cluster, 18 cells).
