A premature stop codon in the third transmembrane domain, which truncates more than 40% of the protein.
Amino acid replacement: W186term.
G21511503A
W186term
Reported amino acid change appears to be relative to M6-PB. 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 curator based on reported amino acid change.
M6W186stop/Df(3L)BSC419 embryos exhibit over-elongated dorsal trunks.
