| KCNK1 | Potassium channel subfamily K member 1; Ion channel that contributes to passive transmembrane potassium transport and to the regulation of the resting membrane potential in brain astrocytes, but also in kidney and in other tissues. Forms dimeric channels through which potassium ions pass in accordance with their electrochemical gradient. The channel is selective for K(+) ions at physiological potassium concentrations and at neutral pH, but becomes permeable to Na(+) at subphysiological K(+) levels and upon acidification of the extracellular medium. The homodimer has very low potassium [...] (336 aa) | ||||
| KCNK6 | Potassium channel subfamily K member 6; Exhibits outward rectification in a physiological K(+) gradient and mild inward rectification in symmetrical K(+) conditions; Belongs to the two pore domain potassium channel (TC 1.A.1.8) family. (313 aa) | ||||
| KCNK7 | Potassium channel subfamily K member 7; Probable potassium channel subunit. No channel activity observed in vitro as protein remains in the endoplasmic reticulum. May need to associate with an as yet unknown partner in order to reach the plasma membrane; Belongs to the two pore domain potassium channel (TC 1.A.1.8) family. (307 aa) | ||||
