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

Heteromultimer with KCNG3, KCNG4 and KCNV2 By similarity.

Subcellular location

Membrane; Multi-pass membrane protein.

Domain

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

The tail may be important in modulation of channel activity and/or targeting of the channel to specific subcellular compartments.

Sequence similarities

Belongs to the potassium channel family. C (Shaw) (TC 1.A.1.2) subfamily. Kv3.1/KCNC1 sub-subfamily. [View classification]

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Select]
Isoform KV3.1 (identifier: P15388-1)
