Imprecise excision of the progenitor insertion, resulting in a 448bp deletion which includes part of the first exon (including the translation start site) and all of the second exon of veli.
448 bp deletion resulting from the imprecise excsion of P{EP}veliGE20172, which extends from the insertion site into veli.
Mutants show a 30% reduction in the number of boutons/muscle surface area at the neuromuscular junction (NMJ) compared to controls. The mean projection area of type Ib boutons at the NMJ is increased by 63% in mutants compared to controls.
veli66 mutant heads do not show any size differences compared to wild-type heads.
Photoreceptor cells of mutant flies kept in the dark for 13 days have a wild-type morphology. The mutants show light-dependent retinal degeneration after 7 days of constant light exposure which can be prevented by raising the flies on a medium lacking vitamin A.
veli66 is a suppressor of neoplasia phenotype of Scer\GAL4rn-GAL4-5, crbintra.UAS
veli66 is partially rescued by Scer\GAL4RapGAP1-OK6/veliUAS.Tag:FLAG/Scer\GAL4C57
Expression of veliScer\UAS.T:Zzzz\FLAG under the control of both Scer\GAL4OK6 and Scer\GAL4C57 largely rescues the increased projection area of type Ib boutons at the neuromuscular junction which is seen in veli66 mutants.
