Figure 5. Light-dependent distribution of transducin β subunit (Tβ)
In the dark (left panels), Tβ is mainly distributed within the rod outer segments (ROS) in wild type and Grk1-/-/Arr-/- retinas. In the light (right panels), it is present throughout the entire photoreceptor layer. In Grk1-/-/Gnat1-/- double knockout retinas (middle panels), Tβ appears equally distributed throughout the photoreceptors independent of light and dark. A: Wild type (wt) retinas. B: Grk1-/-/Gnat1-/- retinas. C: Grk1-/-/Arr-/- retinas. RIS, rod inner segments; ONL, outer nuclear layer; OPL, outer plexiform layer. Bar represents 40 μm.
