Afadin-deficient mice, whose outer-retinal lamination and photoreceptor synapses are severely disrupted, nonetheless partially retain retinal neural circuits and visual function.

Top row: The cryo-ET averages of the gap junction channels (left) revealed striking caps (right; purple) on the inside of the cell. Bottom row: The gap junctions (light blue) allow cells to ...
