Term Information [More information on ion channel activity]

Accession
GO:0005216
Name
ion channel activity
Ontology
molecular_function
Synonyms
None
Definition
Enables the facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. May be either selective (it enables passage of a specific ion only) or non-selective (it enables passage of two or more ions of same charge but different size).
