Members of this family are found in the extracellular region of the cholecystokinin A receptor, where they adopt a tertiary structure consisting of a few helical turns and a disulphide-crosslinked loop. They are required for interaction of the cholecystokinin A receptor with it's corresponding hormonal ligand [1].	Domain
