Nucleotide substitution: C836T.
Amino acid replacement: R279Q.
The mutation introduces a stop codon in the region encoding the homeodomain; consequently, it is likely a strong loss-of-function allele.
Amino acid replacement: ??term.

The reported nucleotide change is relative to the non-coding strand.
Mutants show two or more cells (rather than one cell) in the same thoracic hemisegment expressing P{FMRFa-EGFP.Tv}, a marker for the six Ap4 neurons in the developing ventral nerve cord, and extra expression of eya, which identifies the four Ap cluster neurons.
Isolated in a screen for altered expression of P{FMRFa-EGFP.Tv}, which is normally expressed in only six cells of the ventral nerve cord. It was mapped to the ind gene via whole-genome sequencing, deletion mapping and complementation tests with mutant alleles.
