Nucleotide change:

A6659291T

Reported nucleotide change:

A2485013T

Amino acid change:

term186L | twr-PA

Reported amino acid change:

term186L

Comment:

A mutation in the stop codon results in its replacement by Leu, causing an addition of 12 amino acids to be added to the C-terminal end of the protein.

      twr1/twr2 flies have a rough eye phenotype with disorganisation of the ommatidia and degenerative photoreceptors.

      (Wang et al., 2010)

      The average number of crystal cells per embryo is reduced in homozygous stage 13-14 embryos (raised at the nonpermissive temperature of 30oC) compared to wild type.

      (Milchanowski et al., 2004)

      Mutant eye (rough surface) and bristle (reduced and twisted) phenotype at 25oC and lethal at 28oC.
