Figure 7


Fig. 7. Rst function is required to regulate cell surface levels of Tkv in the Drosophila pupal retina. (A,D,G,J) Levels of cell-surface Tkv in pupal retinas. (B,E,H,K) Matched anti-Armadillo staining to visualize cells. (C,F,I,L) Overlay. Genotype and developmental stages (hours APF) are indicated at the left; wt, wild type. Green arrows indicate cell membranes where Tkv is localized. Red arrows indicate sensory bristles, which accumulated high levels of Tkv. Mutants in rst failed to downregulate surface Tkv protein in IPCs (G,J; compare with D).
