 Two-pore-domain potassium channel

Two-pore-domain potassium channels (K2P channels) are a family of ion channels that facilitate the movement of potassium ions (K+) across cell membranes. These channels are characterized by their unique structure, which features two pore domains within a single polypeptide chain. This dual-pore configuration differentiates them from other types of potassium channels, which typically have a single pore domain.
