A 824 base pair fragment from the n-syb region, including the putative endogenous n-syb promoter, is followed by sequence encoding a lexA::p65 driver. The driver sequence has been optimized for Drosophila codon usage. An Hsp70 transcriptional terminator is present.
EcollexAGMR57C10 drives pan-neuronal expression. In the adult wing, EcollexAGMR57C10 drives expression in both mechanosensory and chemosensory neurons.
