Band-3 protein-mediated anion conductance of the red cell membrane. Slippage vs ionic diffusion.
The band 3 protein-mediated, valinomycin-induced KCl efflux continues to increase with increasing [KCl] when the Cl-/Cl- equilibrium exchange becomes saturated. This suggests the existence of a band 3-mediated component of Cl- flux that contributes to the electrical conductance without being related to slippage; i.e., equilibration of the unloaded transport protein between the two membrane surfaces.
