Cell receptors: of voids and void fillers
Cell receptors: of voids and void fillers
Nearly all vital functions in the human body are regulated by so-called G protein-coupled receptors on the cell surface. These receptors thus serve as attractive drug targets to treat various diseases. Researchers have now discovered that empty spaces inside these receptors are important for their activation and thus for relaying messages to the inner cell.
