Biophysical binding and structural prediction studies reveal that Tetraspanin12 directly binds the ligand Norrin, in a manner that is negatively cooperative with Norrin-Fzd4 binding and competitive with Norrin-LRP5/6 binding.
In congenital stationary night blindness type 2, Cav3 channels may maintain cone synaptic output and visual function provided that the nonconducting role of Cav1.4 in cone synaptogenesis remains intact.

Targeted manipulations on organotypic cultures show that the retina switches between at least four different metabolic pathways, each with different yields and kinetics, to dynamically adapt to momentaneous energy needs.
