Description

cv-d13 has a four nucleotide deletion after the codon for T193 that is predicted to add 16 erroneous amino acids and a stop codon.

A 4 bp deletion after the codon for T193 which leads to a truncation that removes all of the DUF1943 and VWD domains and most of the Vg domain.

Detailed Description
Statement
Reference

84% of mutants have no posterior crossvein (PCV), 16% have a floating PCV, 0% have a detached PCV, 0% are normal.

Homozygotes are viable and fertile, whose only visible external defects are disruption of the posterior crossvein (either partially or wholly absent) and, occasionally, the distal tip of vein L5, and a slight variable reduction in wing size.

Scer\GAL4tub.PU-mediated expression of cv-dScer\UAS.T:SV5\V5 results in complete rescue of the cv-d13 posterior crossvein phenotype.

Scer\GAL4unspecified-mediated expression of cv-dScer\UAS.T:SV5\V5 rescues posterior crossvein development in cv-d13 mutants. However, Scer\GAL4unspecified-mediated expression of cv-dΔDUF1943+VWD.Scer\UAS.T:SV5\V5, cv-dΔVWD.Scer\UAS.T:SV5\V5 or cv-dΔVg.Scer\UAS.T:SV5\V5 does not rescue posterior crossvein development in cv-d13 mutants.
