KCNK4

Gene
Kcnk4
Protein
Potassium channel subfamily K member 4
Organism
Mus musculus
Length
398 amino acids
Function
Voltage-insensitive potassium channel (PubMed:9628867). Channel opening is triggered by mechanical forces that deform the membrane. Channel opening is triggered by raising the intracellular pH to basic levels (By similarity). The channel 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 raised to 42 degrees Celsius (By similarity). Plays a role in the sensory perception of pain caused by pressure (PubMed:19279663). Plays a role in the perception of pain caused by heat (PubMed:19279663).
Similarity
Belongs to the two pore domain potassium channel (TC 1.A.1.8) family.
