Cell biology: A new view of photoreceptors

Franck Pichaud & Claude Desplan

Top

The light-gathering structures in our eyes are specialized membranes found on cells known as photoreceptors. Two studies show that a protein called Crumbs is crucial for the development of these membranes.

The striking conservation of gene function from fruitflies to humans is under the spotlight again. On pages 143 and 178 of this issue, Pellikka and colleagues1 and Izaddoost and co-workers2 describe the role of the Crumbs protein in controlling the development of photoreceptors — the light-detecting cells in the eye — in fruitflies.

  1. Franck Pichaud and Claude Desplan are in the Department of Biology, New York University, 1009 Main Building, 100 Washington Square East, New York, New York 10003-6688, USA.
