A 3844 base pair fragment from the flanking non-coding or intronic region of Vsx2 is fused upstream of a Drosophila core synthetic promoter (DSCP) followed by sequence encoding a lexA::p65 driver. The driver sequence has been optimized for Drosophila codon usage. An Hsp70 transcriptional terminator is present.
Comment: A FLP/FRT strategy shows P{GMR71G01-lexA} drives expression in adult ingestion neuron 1 when combined with TI{GAL4::p65}CCKLR-17D3GAL4::p65.
A FLP/FRT intersectional strategy shows expression of EcollexAGMR71G01 in adult doublesex pC1 (female and male) neurons when combined with ScerGAL4dsx.Δ2.
Expression driven by EcollexAGMR71G01 was restricted to a subset of adult fruitless pMP-e (male) neurons when combined with ScerGAL4dsx.Δ2 in a FLP based intersection strategy.
EcollexAGMR71G01 drives expression in a subset of adult doublesex pC1 (male) neuron that also have expression driven by EcollexAfru.P1.
EcollexAR71G01 drives expression in a subset of neurons in the adult CNS, including the male-specific P1 (pMP-e) neurons in the brain. The P1 neurons overlap with the expression of ScerGAL4fru.P1.B or ScerGAL4dsx-GAL4 in males. A small number of abdominal ganglion neurons and glial cells are also detected when expressing both EcollexAR71G01 and ScerGAL4dsx-GAL4.
