The QF driver coding sequence, with a minimal P-element promoter and an Hsp70 polyA site, has been inserted into a 110kb BAC clone (CH321-85L03) which contains genomic DNA that covers the P{GawB}Mz19 enhancer trap insertion site.
Optogenetic activation (using Crei\ChR2T159C.10xQUAS.Tag:HA with 470 nm (Blue) light) of Ncra\QFMz19.PH neurons in the adult results in a fast excitatory postsynaptic potential in the CSD neuron, relative to controls, that can be blocked by mecamylamine.
