Deletion of amino acids 412-566, inclusive, which encode EGF repeats 10-13 (repeats 11 and 12 contain the Dl binding sites). EGF repeats 9 and 14 are fused.
When expression is driven by Scer\GAL4da.G32 in a wild type background, the resulting phenotype resembles that of puc1 mutants.
NFLNΔ10-12.UAS/Scer\GAL4da.G32 partially rescues Nunspecified
Scer\GAL415J2/NFLNΔ10-12.UAS fails to rescue Nl1N-ts1
Expression of NFLNΔ10-12.Scer\UAS under the control of Scer\GAL415J2 fails to rescue the Nl1N-ts1 axon phenotype.
Partially rescues the neurogenic phenotype of N mutants, with rescue only evident on the dorsal surface.
