Figure 1.
Light-dependent redistribution of arrestin and transducin. The schematic drawing of a rod cell is adjacent to immunofluorescence images of retinal slices immunostained for arrestin and Gαt. The retinas were obtained from light- or dark-adapted mice. OS, outer segments containing the rhodopsin-harboring discs; IS, inner segments; ONL, outer nuclear layer; OPL, outer plexiform layer, which contains photoreceptor synaptic termini.
