UAS regulatory sequences drive expression of a full-length nerfin-1 open reading frame (ORF) that is tagged at the C-terminal end with three copies of the Tag:HA epitope. The ORF is flanked by a pair of incompatible FRT sites (FRT5 and FRT2), which allows for future in vivo exchange of either the promoter or tag sequence.
Expressing nerfin-1UAS.ORF.GW.Tag:HA under the control of Scer\GAL4elav-C155 results in mildly disorganized Fas2-immunopositive fascicles and axon pathfinding defects in ap-expressing neurons, which fail to extend towards the medial-most Fas2-immunopositive fascicle in the embryonic ventral nerve cord. The number of ap-expressing neurons is similar to that of wild-type controls.
Expression of nerfin-1Scer\UAS.ORF.GW.T:Ivir\HA1 under the control of Scer\GAL4Bx-MS1096 results in male flies with almost complete wing loss at 18[o]C.
