Fig. 2. Frtz is proximally localised under control of polarity gene activity. Drosophila 28-hour pupal wings immunolabelled for Frtz (magenta in A-G, white in A'-G') and/or Fmi (A, blue; H, magenta), and clonal marker (lacZ or GFP, green) or EGFP-Fy (green in H, white in H'). Arrowheads indicate proximally enriched localisation of protein. (A,A') frtz³³ clone. (B,B') fy² clone. (C,C') in^IH56 clone. (D,D') mwh¹ clone. (E,E') stbm⁶ clone. (F,F') pk^{pk-sple- 13} clone. (G,G') fz²¹ clone. (H,H') Mosaic expression of EGFP-Fy induced from a P{w+, ActP-FRT-PolyA-FRT-EGFP-Fy} transgene using hsFLP expression. Scale bar: 10 µm.
