Drug discovery is shifting from static snapshots to moving pictures. Instead of inferring how medicines work from end results ...

Receptor proteins, expressed on the cell surface or within the cell, bind to different signaling molecules, known as ligands, initiating cellular responses. Taste receptors, expressed in oral tissues, ...

A new study found that a single mutation to the hemagglutinin protein of an H5N1 virus isolated from a dairy worker in Texas this spring switched the protein’s binding specificity from avian- to human ...

For the first time, researchers have determined how a human olfactory receptor captures an airborne scent molecule, the pivotal chemical event that triggers our sense of smell. Whether it evokes roses ...
