Once bound to a wide variety of extracellular ligands, GCPRs undergo a conformational change and relay information to intracellular secondary messengers <ref name="Thal">Thal, David M., et al. "Structural insights into G-protein-coupled receptor allostery." Nature, Nature Publishing Group, 04 July 2018, https://www.nature.com/articles/s41586-018-0259-z</ref>. This G protein activation results in a cellular response dependent on the ligand bound and location of the GPCR in the body. GCPRs can be broken down into five families: the rhodopsin family (class A, 701 members), the secretin family (class B, 15 members), the adhesion family (24 members), the glutamate family (class C, 15 members), and the frizzled/taste family (class F, 24 members)². All of the families have a similar transmembrane (TM) domain consisting of seven ɑ-helices complexed with intracellular G proteins. | ||
