Evidence for two types of beta-adrenergic-sensitive adenylate cyclase activities in bovine cerebellum

A latent, as well as an expressed form of adenylate cyclase coupled to beta-adrenergic receptors is present in intact crude synaptosomal preparations from bovine cerebellum. The latent adenylate cyclase activity was assayed in Krebs-Ringer buffer by [3H]adenine labeling and was found to be coupled to a beta 1-like adrenergic receptor. The externally accessible adenylate cyclase assayed in the same medium with [3H]ATP was stimulated via beta 2-adrenergic receptors.

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
