U6 promoters drive expression of 4 different sgRNAs, that each target Pzl.
Knock-out of Pzl in Cho neurons PzlU6.sgRNA and expressing Spyo\Cas9UAS.Tag:NLS(Unk) under the control of Scer\GAL4iav.PP induces abnormal locomotor behavior, with severely increased periods of head lifting and spontaneous backward movements compared to controls, as well as severely higher frequency of bending their bodies laterally to greater than 90[o], which is rarely observed in wild-type controls.
