Nucleotide change:

G21575066A

Amino acid change:

W1587term | InR-PA; W1587term | InR-PB; W1587term | InR-PC; W1587term | InR-PD

Reported amino acid change:

W1439term

Comment:

Mutation is in the cytoplasmic region.

Comment:

G to A nucleotide change at the second or third position of the wild type Trp codon leads to a nonsense mutation. InR[31] and InR[304] have mutations at adjacent G residues; specific changes for each not reported. The mutation was annotated at the second base of the codon.

      Selective removal of InRE19 function in eye progenitor cells generates flies with strongly reduced eye and head capsule while all other parts are wild-type. Mosaic eyes show photoreceptors that are reduced in size by more than half.

      Alleles of InR form an allelic series based on phenotypic strength: InR339 > InR31 > InR211 > InRE19 > InR353.

      (Brogiolo et al., 2001)

      When in trans with Df(3R)e-D7 the lethal phenotype can be rescued by P{hs-inr}.
