Covalent binding between the ligand and the receptor is not a feature of signal transduction. Signal transduction involves the binding of a signal molecule or ligand to a receptor protein, activating a cascade of intracellular signaling events that ultimately lead to a cellular response. However, this binding is typically non-covalent, meaning that the ligand and receptor interact through weak, reversible interactions such as hydrogen bonding, electrostatic interactions, and van der Waals forces.
