WebAdenosine A3 receptor (ADORA3) is a member of the adenosine receptor group of GPCRs and uses adenosine as an endogenous ligand. Activation of the adenosine A3 receptor by an agonist leads to the binding of Gi1/2/3 or Go protein. The binding of Gi1/2/3 leads to the inhibition of adenylate cyclase, therefore, the concentration of cAMP is reduced.

Ion channels are pore-forming membrane proteins that allow ions to pass through the channel pore. Their functions include establishing a resting membrane potential, shaping action potentials and other electrical signals by gating the flow of ions across the cell membrane, controlling the flow of ions across secretory and epithelial cells, and regulating cell volume. Ion channels are present in the me…
WebMar 12, 2024 · Abstract. Ion channels facilitate the movement of ions across the plasma and organellar membranes. A recent symposium brought together scientists who study ion channels and transporters in immune cells, which highlighted advances in this emerging field and served to chart new avenues for investigating the roles of ion channels in … WebSodium-potassium pump (Na-K pump): This pump pumps 3 Na+ ions out for every 2 K+ ions that it lets in. Sodium Potassium Pump. V-gated ion channels: These channels can be open or closed. The factor that determines whether it is open or closed is the membrane voltage. If it is more positive internally, this can cause the channels to open.
