Shows a reduction is positive phototaxis at 1 week after eclosion.
Mutant adults show only weak positive phototaxis compared to controls, although the phototactic profile improves greatly in the mutant flies between 3 and 10 days after eclosion.
Induced on: ca1
Identification: by reduction in/loss of Gycα99B protein on a Western Blot. In terms of immunoreactivity on a Western Blot (most to least) Gycα99B2 < Gycα99B1 = Gycα99B3 = Gycα99B5.
