Signal transduction: The rhodopsin story continued

Determination of the architecture of an invertebrate photoreceptor protein, squid rhodopsin, is a notable event. It illuminates the mechanism of invertebrate vision and a ubiquitous intracellular signalling system.

Many invertebrates have excellent visual systems1. Squid, for example, are formidable hunters that rely on their acute visual abilities to catch their prey.
