The ubiquitous snRNA:U6:96Ac promoter drives expression of two sets of sgRNAs (GGAAAAAACTACGGAAAATG and TTTCGCGTTCTGGCTATAAA) targeting the short isoform-specific exon 6 of LpR1.
CRISPR/CAS9 mutagenesis of LpR1 long isoform in Pdf-positive neurons (LpR1U6:3.2xgRNA.short, Scer\GAL4P2.4.Pdf>Spyo\Cas9UAS.Tag:NLS(Unk)) leads to LNv neurons in the larval brain to show decreased dendritic volume.
