Fig. 6. The interaction between arrestin and AP-2 is required for norpA-mediated retinal degeneration. All panels show cross sections (0.5 µm) of Drosophila retinas from (A) wild-type, (B) norpA, (C) norpA; arr2K391A and (D) norpA; arr2R393A. Dark-reared flies were treated with 5 days of constant room light then fixed and sectioned as described in Materials and Methods.
