title: Molecular cloning, functional expression, and chromosomal localization of the human cholecystokinin type A receptor.
abstract: The results presented here describe for the first time the molecular cloning of the human CCKA-R. Expression of the recombinant receptor shows the expected subtype pharmacology and coupling to phosphoinositide hydrolysis reported for the native human CCKA-R. This knowledge will enhance our understanding of its distribution, pharmacology, and structure and will improve our understanding of its physiological role in the gastrointestinal and nervous systems in humans. Ultimately, this should hasten the understanding and therapy of gastrointestinal and neuropsychiatric disorders.
