A guide RNA (gRNA) designed to target the 5' half of the coding sequence of Lis-1 is under the control of the snRNA:U6:96Ac promoter.
The expression of Lis-1gRNA.snRNA:U6:96Ac under the control either of Scer\GAL4GMR91H05 or of the split-GAL4 Hsap\RELAAD.R17A04 + Scer\GAL4DBD.R68A06 combo does not lead to any giant fiber anatomical defects, as compared to controls.
