Potassium channel subfamily K member 4 (Kcnk4)

Voltage-insensitive potassium channel (PubMed:9628867). Channel opening is triggered by mechanical forces which deform the membrane.

Channel opening is triggered by raising the intracellular pH to basic levels (By similarity). The station is inactive at 24 degrees Celsius (in vitro); raising the temperature to 37 degrees Celsius increases the frequency of channel opening, with a further increase in channel activity when the temperature is increased to 42 degrees Celsius (By similarity).
