Deletion of nucleotides 553-558, resulting in an in frame deletion of two conserved residues (V143 and K144) at the beginning of helicase-like motif III.
Position of mutation on reference sequence inferred by FlyBase curator based on author statement: Deletion of nucleotides 553-558, resulting in an in frame deletion of two conserved residues (V143 and K144) at the beginning of helicase-like motif III. (adjusted for additional 43 residues at N terminus in annotated protein relative to reported protein).
Hemizygous male larvae are sensitive to HN2 and MMS. Homozygous females produce diplo-X and nullo-X exceptions at roughly the same frequency.
