Protein Structure

UniProt Annotation

Function

Pore-forming (alpha) subunit of voltage-gated potassium channel. Elicits a non-inactivating outward rectifying current. Channel properties may be modulated by cAMP and subunit assembly.

Subcellular Localization

Membrane; Multi-pass membrane protein.

Disease Associations

Tissue Specificity

Detected in brain, skeletal muscle, heart, placenta, lung and liver, and at low levels in kidney.
