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.
ScerGAL4NP2119 drives expression in mushroom body extrinsic neurons, including mushroom body medial lobe arborizing neuron 1, mushroom body pedunculus-medial lobe and vertical lobe arborizing neuron 2, that innervate mushroom body gamma lobe slices 1 and 5, mushroom body beta lobe slices 1 and 2, mushroom body beta' lobe slice 2, and mushroom body alpha lobe slices 1, 2 and 3.
ScerGAL4NP2119 drives expression in two adult multiglomerular antennal lobe projection neurons innervating antennal lobe glomeruli D, VA5, VA6DC3, VA1d and VA1v.
