molecular_function Term "outward rectifier potassium channel activity" (GO:0015271)

Term Name	outward rectifier potassium channel activity
Term Accession	GO:0015271
Aspect	molecular_function
Synonyms (0)	None.
Definition	Catalysis of the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel. An outwardly rectifying current-voltage relation is one where at any given driving force the outward flow of K+ ions exceeds the inward flow for the opposite driving force.
Comment	None
