UAS regulatory sequences drive expression of the Fas2 PA- isoform (PA isoform in which the PEST domain has been deleted) which is tagged at the C-terminal end with Tag:FLAG. The Fas2 PDZ binding sequence (KNSAV) has been reinserted following the Tag:FLAG tag, as this sequence is important for Fas2 expression in the mushroom body.
Overexpression of Fas2Scer\UAS.PEST-.KNSAV.T:Zzzz\FLAG with Scer\GAL4Tab2-201Y does not inhibit pruning.
Co-expression of bskDN.Scer\UAS.cUa with Fas2Scer\UAS.PEST-.KNSAV.T:Zzzz\FLAG by Scer\GAL4Tab2-201Y results in mushroom body pruning defects.
