Fig. 6. Staufen localization is normal in sec5E13
egg chambers. Egg chambers stained for Staufen (green), F-actin
(phalloidin, red) and DNA (DAPI, blue). (A) In wild-type egg chambers,
Staufen concentrates in the oocyte during early oogenesis (egg-chamber 1).
After stage 7 and repolarization of the oocyte MT cytoskeleton, Staufen is
transiently detected in the middle of the oocyte (egg-chamber 2). From stage 9
onwards, Staufen forms a tight crescent at the posterior pole (egg-chamber 3).
(B) In sec5E13 egg chambers, all steps of Staufen
localization appear normal.
