Gene Gene information from NCBI Gene database.
Entrez ID 3776
Gene name Potassium two pore domain channel subfamily K member 2
Gene symbol KCNK2
Synonyms (NCBI Gene)
K2p2.1TPKC1TREKTREK-1TREK1hTREK-1chTREK-1e
Chromosome 1
Chromosome location 1q41
Summary This gene encodes one of the members of the two-pore-domain background potassium channel protein family. This type of potassium channel is formed by two homodimers that create a channel that leaks potassium out of the cell to control resting membrane pote

Protein name Potassium channel subfamily K member 2 (Outward rectifying potassium channel protein TREK-1) (TREK-1 K(+) channel subunit) (Two pore domain potassium channel TREK1) (Two pore potassium channel TPKC1) (K2P2.1)
Protein function K(+) channel that conducts voltage-dependent outward rectifying currents upon membrane depolarization. Voltage sensing is coupled to K(+) electrochemical gradient in an 'ion flux gating' mode where outward but not inward ion flow opens the gate.
