Chemoattractant-induced membrane hyperpolarization in Dictyostelium discoideum. A possible role for cyclic GMP.

FEBS letters - 26 Nov 1990

Van Duijn B, Wang M

Abstract excerpt

Membrane potentials of the cellular slime mold Dictyostelium discoideum were monitored after chemotactic stimulation by measuring the distribution of the lipophilic cation tetraphenylphosphonium. Stimulation with the chemoattractant cAMP induces a transient membrane hyperpolarization which reache...
