Calmodulin interacting with the rod CNG ion channel (IMAGE)
Caption
Researchers deciphered the structure of an ion channel from the rod cells of the eye (shown in blue) while it interacts with the protein calmodulin (purple). This interaction is important to the function not only of the ion channel in the eye, but also of ion channels in other parts of the body such as the heart. (Image: Dina Schuster)
