Contains a 1100bp deletion tha removes exon 4 and part of exon 3. This results in a mis-splicing of exon 2 to exon 5 and a frameshift at amino acid 109 that yields a 110 amino acid truncated protein.
fertile (with Df(2L)03832MR1), with Scer\GAL4elav-C155, nompBΔX.UAS
nompB1/Df(2L)03832MR1 males carrying nompBΔX.Scer\UAS driven by Scer\GAL4elav-C155 are fertile. The offensive competitive ability of sperms from these males is also unaffected; the last-male sperm precedence usually seen is unaffected.
Flies are uncoordinated showing frequent leg crossing and wings held up or out. Walking and righting ability is impaired. Spontaneous or induced (by light or mechanical stimuli) activity is vigorous. Mechanoreceptor potentials are invariably absent in thoracic macrochaete bristles. The sound evoked response (measured via the antennal nerve) is eliminated. ERGs are normal.
nompB1/Df(2L)03832MR1 is rescued by Scer\GAL4elav-C155/nompBΔX.UAS
