General Information
Term voltage-gated potassium channel activity ID (Ontology) GO:0005249 (Gene Ontology)
Definition Enables the transmembrane transfer of a potassium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.[ ISBN:0815340729 ]
Also Known As "voltage gated potassium channel activity" ; "voltage-dependent potassium channel activity" ; "voltage-gated potassium ion channel activity" (for all, see Synonyms field below)
