G protein coupled receptors (GPCRs) are recognized as the largest known class of integral membrane proteins and are divided into five families; the rhodopsin family (class A), the secretin family (class B), the adhesion family, the glutamate family (class C), and the frizzled/taste family (class F). Roughly 5% of the human genome encodes g-protein-coupled receptors which are responsible for the transduction of endogenous signals and the instigation of cellular response. The variants all contain a similar seven α-helical transmembrane domain (TMD or 7TMD) that, once bound to its peptide ligand, undergoes conformational change and tranduces a signal to coupled, heterotrimeric G proteins which initiate intracellular signal pathways and generate physiological and pathological processes. <ref>DOI 10.1371/journal.pcbi.0020013</ref> | G protein coupled receptors (GPCRs) are recognized as the largest known class of integral membrane proteins and are divided into five families; the rhodopsin family (class A), the secretin family (class B), the adhesion family, the glutamate family (class C), and the frizzled/taste family (class F).
