Description preview

This proposal addresses one of the most fundamental unsolved problems in vision: the molecular and cellular
mechanism responsible for building and maintaining the light-sensitive organelle of vertebrate photoreceptor cells,

the outer segment. The outer segment is a ciliary structure filled with a stack of disc membranes, which provide
