Fig. 4. Scrib domain regulation of apical protein localization in stage 15 neuroblasts. Embryonic neuroblasts stained for the apical proteins aPKC or Dlg (green) and mitotic markers
-tubulin or PhosphohistoneH3 (PH3; red). Stage 15 embryos, apical up for all images. Scrib domain abbreviations given in Fig. 1. (A) Wild-type metaphase neuroblast showing apical localization of aPKC and Dlg. (B-H) scrib1/scrib1 metaphase neuroblasts expressing the indicated Scrib:myc transgene (progeny from UAS-scrib:myc x worniu-gal4). All show normal localization of aPKC and Dlg.
