Reported nucleotide change:

G?A

Amino acid change:

W147term | kkv-PA; W147term | kkv-PC; W147term | kkv-PD

Reported amino acid change:

W147term

Comment:

G to A nucleotide change at the second or third position of the Trp codon leads to a nonsense mutation (exact site of mutation unspecified). Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.

      Reference

      kkv404 terminal tracheal cell clones exhibit low-penetrance discontinuities of the apical membrane whereas isolated kkv404 clones in the dorsal trunk form cysts ('divots') in the gas-filled lumen in heat-killed mosaic third instar larvae.

      (Rosa et al., 2018)

      kkv404 mutants display a strong terminal cell gas-filling defect. Auto-cellular tubes also show this gas-filling defect. Dorsal trunk cells show mild lumen constriction.
