General annotation (Comments)

Function

Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.

Subunit structure

Heterotetramer of potassium channel proteins By similarity.

Subcellular location

Membrane; Multi-pass membrane protein.

Domain

The N-terminus may be important in determining the rate of inactivation of the channel while the tail may play a role in modulation of channel activity and/or targeting of the channel to specific subcellular compartments.

The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.

Sequence similarities

Belongs to the potassium channel family. A (Shaker) (TC 1.A.1.2) subfamily. Kv1.6/KCNA6 sub-subfamily. [View classification]
