microtubule & oocyte (with BicC4)
nurse cell (with BicC4)
A zone along the anterior region of the oocyte shows a significantly higher concentration of microtubules in BicC3/BicC4 egg chambers compared to wild type.
BicC3/BicC4 egg chambers often show incomplete nurse cell dumping. The actin cables that normally restrain the nurse cell nuclei are absent in the mutant egg chambers, and nurse cell nuclei are often seen to have entered the ring canals.
Dominant haplo-insufficiency phenotype, eggs produced have fused dorsal appendages.
