UAS drives expression of the Fas2-A-PEST- coding sequence in which the final 101 bp of the ORF is modified such that the last base of every codon is altered to maintain the amino acid sequence while inhibiting targeting by P{UAS-Fas2.RNAi.A}.
Scer\GAL4da.G32-mediated expression of Fas2PEST-.RNAiResistant.Scer\UAS fully rescues the reduction in bouton number induced by Fas2dsRNA.Scer\UAS.A expression.
