Triggers a transduction chain that in turn produces a measurable response  Usually made up of at least 2 domains  Ligand –binding domain  Effector/catalyic domain  Can be located at:  Cell surface  Within the cytoplasm or  Inside the nucleus  Receptors  determine the quantitative relations between dose/concentration of drug and pharmacologic effects  are responsible for selectivity of drug action  Selectivity of Receptors › If receptor serves a function that is common to most cells  Drugs binding to it  Widespread effect › If receptor unique to only a few types of differentiated cells  Drugs binding to it  More specific effect  Subtypes of Receptors Certain receptors have subtypes Example: Adrenergic receptors Noradrenalin β1 Receptors in Heart β2 Receptors in Bronchioles  4 main classes of receptors transmembrane signalling › Classification based on their mechanism of › Each uses a different strategy to overcome the barrier posed by lipid bilayer of the plasma membrane 1.

In nucleus 1 2 3  Ligands: usually lipid soluble, → Able to cross the plasma membrane → Act on these intracellular receptors  Examples: Steroids, Thyroid hormones, Glucocorticoids Binding of ligand with these receptors could lead to changes in intracellular activities   Has 3 distinct 3 domains 1.
