Protein

Potassium voltage-gated channel subfamily A member 6

Gene

Kcna6

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

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.

Domaini

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.
