| Mechanism of Action | KCNK2 encodes a two-pore domain potassium channel (TREK-1) that regulates neuronal excitability, membrane potential, and cellular responsiveness to mechanical and chemical stimuli in the central nervous system. In neurodegeneration, TREK-1 modulation can influence neuronal survival, mitochondrial function, and potentially mitigate oxidative stress and excitotoxicity through precise potassium conductance regulation. |
