WebA key property of signal transduction pathways is that one signal molecule binding to a receptor protein in the cell membrane can result in several thousand events at the end of the pathway. Some disease-causing microbes attack the body by turning on or off specific signal transduction pathways. WebThe epinephrine receptor (β-adrenergic receptor) undergoes accommodation (physiologic response reduced upon repeated stimulation) to sustained, but unchanging, concentrations of epinephrine. As the G s subunits dissociate from the receptor, the β-adrenergic receptor kinase phosphorylates the cytoplasmic domain of the receptor (see Fig. 5-8 ).
