β-COP Suppresses the Surface Expression of the TREK2.

ABSTRACT: K2P channels, also known as two-pore domain K⁺ channels, play a crucial role in maintaining the cell membrane potential and contributing to potassium homeostasis due to their leaky nature. The TREK, or tandem of pore domains in a weak inward rectifying K⁺ channel (TWIK)-related K⁺ channel, subfamily within the K2P family consists of mechanical channels regulated by various stimuli and binding proteins. Although TREK1 and TREK2 within the TREK subfamily share many similarities, β-COP, which was previously known to bind to TREK1, exhibits a distinct binding pattern to other members of the TREK subfamily, including TREK2 and the TRAAK (TWIK-related acid-arachidonic activated K⁺ channel). In contrast to TREK1, β-COP binds to the C-terminus of TREK2 a
