g, Single-channel conductance; PX, permeability to ion X; V-dep, voltage dependence of channel open probability (in some cases inferred from rectification of the macroscopic current in nearly symmetrical solutions); NR, nonrectifying; OR, outwardly rectifying; IR, inwardly rectifying; native, channels originating in a native membrane, in some cases transferred to an artificial bilayer; exogenous, channels made by exogenous expression.
