Scer\GAL4dsx.KI drives expression in four of twelve neuroblasts in the larval terminal abdominal neuromere; in female larvae, these neuroblasts die during mid-third instar.
Drives expression in doublesex-expressing neurons and neuroblasts, and in oenocytes, at all developmental stages.
Scer\GAL4dsx.KI drives expression in non-neuronal tissues, including unidentified sub- and peri-cuticular cells.
Scer\GAL4dsx.KI drives expression in the posterior part of the thoracico-abdominal ganglion and a subset of neurons in the adult brain. In males expression in the brain is stronger than in females and additional expression in more anterior parts of the thoracico-abdominal ganglion are detected.
Scer\GAL4dsx.KI drives expression in 3 clusters of neurons in the adult female genital tract: one cluster of 1 neuron in the lateral oviduct (which co-localises with Avic\GFPEGFP.ppk.1) and two clusters in the uterus. An anterior one with 3 neurons (which also express Avic\GFPEGFP.ppk.1) and one more posterior with 7 neurons which co-express Avic\GFPEGFP.ppk.1, with 3 neurons of those also expressing Ecol\lexAfru.P1.T:Hsim\VP16. In combination with Scer\FLP1250, Scer\GAL4dsx.KI drives expression in 27, out of a total of 300 neurons, in the abdominal ganglion of adult females. These neurons include four ascending abdominal ganglion neurons that terminate in the subesophageal ganglion, and two subesophageal ganglion descending neurons that innervate the uterus. Sex specific differences were observed, with the majority of males displaying only one ascending neuron, and half of the males displaying two descending neurons.
Scer\GAL4dsx.KI drives expression in several cell clusters in the CNS throughout development, with some of the cell clusters being either male specific (SN, TN1 and TN2), or composed of more cells in males. In the adult CNS, expression is observed in 900 neurons in males (9 clusters) and 700 neurons in females (6 clusters). Co-localisation with fru protein is observed in some clusters including pC1, pC2, pC3 and in the abdominal ganglion.
