G protein-coupled receptors, often abbreviated GPCRs, are an abundant superamily of proteins also known as seven-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein-linked receptors (GPLRs). G protein-coupled receptors are cell surface signalling proteins involved in many physiological functions and in multiple diseases. they are also the target of the majority of all modern medicinal drugs [1][2].
Rhodopsin shares similar membrane topology with the members of the superfamily (Family A of the G protein-coupled receptors which include the seven transmembrane helices, an extracellular N terminus and cytoplasmic C terminus[3].
