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.
ScerGAL4NP6277 drives expression in neurons with cell bodies located lateral to the antennal lobes (AL). Some of the labeled neurons innervate the AL.
In addition to driving expression in antennal lobe local interneurons, ScerGAL4NP6277 is also broadly expressed in many cell types around the antennal lobe and in a subset of olfactory receptor neurons.
Location 2L:6179112-6179113 refined by FlyBase alignment of dbGSS accessions AG219125 and AG217396 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation revised.
