Structure of beta adrenergic receptor
WebThere are three beta adrenoceptor subtypes: beta-1, beta-2, and beta-3. The beta-2 adrenoceptor is the prototypical G protein-coupled receptor and much is known about its structure, function, and regulation. Selective beta-2 agonists include salbutamol, terbutaline, and salmeterol. WebJan 6, 2024 · Thus, β1-adrenergic receptor-mediated recruitment of the ERK1/2 plays a seminal role in the upregulation of CaVα2δ1 in NRVMs independent of the concomitant hypertrophic response. However, the upregulation of CaVβ3 protein levels may be directly dependent on the hypertrophic response of NRVMs.
