Localization of Sec5 in stage 10 oocytes. A-F) Wild type egg chambers or egg chambers from sec61βP1germline clones were stained with Sec5 (red) and Phalloidin (green). In wild type egg chambers (A) or from sec61βP1germline clones (D) Sec5 is at a peripheral location in the oocyte. Co-staining with phalloidin (B and E) shows that both in wild type oocytes and oocytes from the germline clones Sec5 co-localizes at the plasma membrane. n indicates the position of the nucleus (C and F).
