Accession
GO:0015267
Name
channel activity
Ontology
molecular_function
Synonyms
channel/pore class transporter activity, nonselective channel activity, alpha-type channel activity, channel-forming toxin activity, pore class transporter activity, substrate-specific channel activity, pore activity
Alternate IDs
GO:0015249, GO:0015268, GO:0022838
Definition
Enables the energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. Source: GOC:mtg_transport, ISBN:0815340729
