Term Name: channel activity
Synonyms: alpha-type channel activity, channel-forming toxin activity, channel/pore class transporter activity, nonselective channel activity, pore activity, pore class transporter activity, substrate-specific channel activity
Definition: Enables the energy-independent facilitated diffusion 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.
