Fig. 5. The Kinesin light chain (Klc) and sunday driver are not essential for the posterior localisation of Staufen and Dynein. Localisation of Staufen (A-C) and the dynein heavy chain (D-F) at the posterior pole of the oocyte in wild-type (A,D), sunday driver (syd; B,E) and Klc (C,F) mutant egg chambers. In syd mutant oocytes, the localisation of Staufen (B) and DHC (E) proteins is indistinguishable from wild type (A,D). In Klc mutant egg chambers, Staufen (C) and DHC (F) are transported from the anterior to the posterior as in wild type, although the Staufen posterior crescent is occasionally not as tight as in wild type (I. M. P. and D. St J., unpublished), and the amount of DHC at the posterior is reduced. The mutant clones are marked by the absence of nuclear GFP.
