Cytoskeleton participation in subcellular trafficking of signal transduction proteins in rod photoreceptor cells

Adaptation through translocation

Papers by and, in this issue of Neuron, describe how massive and rapid translocation of specific elements of the phototransduction cascades in different phyla, namely, the G protein (transducin) in vertebrate rods and light-sensitive TRPL channels in the microvillar rhabdomeres of Drosophila, contribute to photoreceptor adaptation.
