Alpha-1 Adrenergic Receptor

Alpha-1 Adrenergic Receptor

The alpha-1 (α1) adrenergic receptor is a G protein-coupled receptor (GPCR) associated with the Gq heterotrimeric G-protein. It consists of three highly homologous subtypes, including α1A-, α1B-, and α1D-adrenergic. Catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) signal through the α1-adrenergic receptor in the central and peripheral nervous systems.

Famous quotes containing the word receptor:

    The disinterest [of my two great-aunts] in anything that had to do with high society was such that their sense of hearing ... put to rest its receptor organs and allowed them to suffer the true beginnings of atrophy.
    Marcel Proust (1871–1922)
