Statement
Reference
Imprecise excision of Mi{ET1}Neto[MB04917], resulting in removal of sequence X: 13391744-13394080, including exon 5 of the predicted Neto gene. This deletion introduces frameshifts and early stop codons, and the Neto ORF is truncated within the first CUB domain.

hide Detailed Description
Statement
Reference
Neto[36] hemizygous embryos have normal overall appearance and completely fill their trachea with gas, but they never hatch into larval stages and they die within 2 days after egg laying. This phenotype is 100% penetrant. Mutant embryos are completely paralysed and lack any body wall peristalsis and hatching movements. Manually hatched animals fail to move or feed.

Comments
The lethality of Neto[36] embryos is rescued to larval stages by expression of Neto[Scer\UAS.T:SV5\V5,T:Zzzz\His6] using Scer\GAL4[da.G32], Scer\GAL4[how-24B] or Scer\GAL4[G14]. Moreover, a number of Neto[36] animals are rescued all the way to viable and fertile adults using Scer\GAL4[how-24B]- or Scer\GAL4[G14]-mediated expression of Neto[Scer\UAS.T:SV5\V5,T:Zzzz\His6]. The lethality of Neto[36] is completely rescued by Dp(1;3)DC270. Scer\GAL4[G14]-mediated expression of Neto[Scer\UAS.T:Avic\GFP-EGFP] rescues Neto[36] mutants to adulthood when the temperature is maintained at 25[o]C. However, if the temperature is reduced to 18[o]C (to reduce Scer\GAL4 expression/activity) when first instar larvae hatch, most animals die at larval-pupal stages and exhibit altered, smaller synapses at third instar larval stage.
