Abstract:Visual signal transduction occurs on the surface of membrane discs stacked inside the ciliary outer segment of photoreceptor cells. Salinas et al. show that discs are formed from ciliary ectosomes whose release is blocked by the protein peripherin/RDS. This explains how photoreceptors transform their primary cilia into the light-sensing outer segment organelle.
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
