Illustration of Arrestin while Docked with Rhodopsin

Caption

This illustration shows arrestin (yellow), an important type of signaling protein, while docked with rhodopsin (orange), a G protein-coupled receptor. GPCRs are embedded in cell membranes and serve an important role in a cellular signaling network. An experiment conducted at SLAC's Linac Coherent Light Source X-ray laser provided an atomic-scale 3-D map of this joined structure.
