For neurotransmitters to generate their effects in other cells, they must bind to a receptor. It is possible for a neurotransmitter to bind to a variety of receptors, which are typically made up of multiple protein subunits. Each of these subunits may have several isoforms. As a result, there are many combinations of neurotransmitter/receptor bindings, each of which can generate its own unique response in the cell.
