Staufen localization and movement in streaming oocytes. Two representative examples of a mat atub- GFP-Staufen oocyte and a nos>Staufen-SunTag oocyte, respectively. Both GFP-Staufen and Staufen-SunTag formed posterior crescents and labeled cytoplasmic particles that were circulated with ooplasmic streaming. Both videos were imaged using identical conditions. To note, Staufen-SunTag labeling is much brighter than the GFP-Staufen. Bar, 50 µm.
