Description

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 fruitless expressing neurons, including in male-specific fruitless neurons, in adults. Drives expression in the larval and adult mushroom bodies, and in a subset of pupal and adult antennal lobe glomeruli.

Scer\GAL4NP0021 drives expression in around 6 uniglomerular antennal lobe projection neurons. Their cell bodies are positioned in the lateral part of the antennal lobe and they project to antennal lobe glomerulus DA1 only. Expression is also detected in one ventrally located multiglomerular projection neuron which innervates glomeruli DA4l, VA1d, VA1v, VL1, VL2a, VM4, VM6, VC5, VP1, VP2, VP3 and VP4.

Scer\GAL4NP0021 drives expression in a subset of neurons in the male pupal brain, including a cluster of neurons located dorsal and medially to the antennal lobe (mAL neurons). Expression is also observed in a subset of neurons in the ventral nerve cord. Almost all neurons that express Scer\GAL4NP0021 also express hb protein. All neurons labelled by Scer\GAL4NP0021 express fru protein.

Expression is observed in ~200 projection neurons in the γ lobe of the mushroom body.

Expressed in clusters of mushroom body neurons that project to the median and lateral bundles. Expression in the corpora pedunculata (mushroom body) includes all known substructures (but may not include all neurons).
