Description

A 3683 base pair fragment from the flanking non-coding or intronic region of Lgr3 is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.

Additional Information
Statement
Reference

ScerGAL4GMR19B09 drives sexually dimorphic expression in the median bundle, where it is expressed more strongly and in more neurons in the female than in the male.

(Meissner et al., 2016)

ScerGAL4GMR19B09 drives expression in around 12 neurons per hemisphere in the central larval brain as well as some neurons in the ventral nerve cord.

(Vallejo et al., 2015)

Approximately 10 ScerGAL4GMR19B09 positive neurons per hemisphere express Lgr3ag5RA, including a pair of bilateral neurons in the larval pars intercerebralis. In the VNC, a further 60 or so neurons also co-express Lgr3ag5RA.
