Many signaling receptors are internalized faster when they are bound to their ligand—a phenomenon known as downregulation. The figure shows the effect of downregulation on the response of the epidermal growth factor receptor to time-varying ligand concentrations. Computational analysis reveals that downregulation enhances the accuracy of signaling receptors. (See Shankaran et al, e101).
