Single ion channels in the slime mold Dictyostelium discoideum.
Single ion channels with different conductances and gating characteristics were observed in the plasma membrane of the slime mold Dictyostelium discoideum by means of the patch-clamp technique in the cell-attached mode. The predominant channel type shows outward current flow, probably carried by K+ ions. The slope conductance of this channel is 9 pS and its probability to be open increases with depolarization of the membrane. The channel is observed from 1 to 8 h after the beginning of starvation.
