Deletion of residues 1722 to 1775. In-frame deletion, removing amino acids 305 to 331 (affecting the first zinc finger but leaving the second zinc finger intact). The number of the base mutated corresponds to the numbering given for the genomic sequence of nos in FBrf0053387, with one correction: an extra three bases (AGA) have been found between bases 1410 and 1411, replacing His 201 with Gln and Ile.

Fails to rescue the abdominal phenotype of embryos derived from nos18 females.
Selected as: a mutation that reverts the female sterile phenotype of flies carrying nosαTub84B.UTR.T:Ivir\HA1.
