intracellular allosteric site GPCRs represent one of the largest and most vital families of cell surface receptors distinct, often less conserved sites on the receptor. This allows for the fine-tuning of receptor activity, leading to more specific and safer drugs. Allosteric binding sites on the receptor are those topographically distinct from (do not exhibit any in their orthosteric binding sites, such as chemokine receptors.
