| Full Name | Potassium Two Pore Domain Channel Subfamily K Member 2 |
| Aliases | TASK1, K2P2.1, TREK-1, TWIK-related potassium channel 1 |
| Chromosome | 1q41 |
| Protein Family | Two-pore domain potassium (K2P) channel family |
| Protein Type | Ion Channel |
| Target Class | Ion Channel |
| Function | Small molecule channel modulation |
| 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. |
