3R:19,016,408..19,016,408 [+]
Nucleotide change:

G19016408A

Amino acid change:

W735term | gukh-PA; W735term | gukh-PE

Reported amino acid change:

W735term

Comment:

Mutation reported relative to isoform PA. 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 base on reported amino acid change.
