GO term:channel activity
Synonym: alpha-type channel activity
Synonym: channel-forming toxin activity
Synonym: channel/pore class transporter activity
Synonym: nonselective channel activity
Synonym: pore activity
Synonym: pore class transporter activity
GO id:GO:0015267
Definition:Catalysis of 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.
