We report the transmembrane voltage-induced lateral reorganization of highly-ordered lipid microdomains in the plasma membrane of living yeast. Different depolarization mechanisms, including the application of ionophores, cell depolarization by an external electric field, and partial depolarization by protein-mediated ion transport or by compromised respiration efficiency, yielded the same results: a significant reduction in the amount of gel-like microdomains in the membrane. The data suggest that the voltage-induced reorganization of lateral membrane structure could play significant role in fast cellular response to acute stress conditions, as well as in other membrane microdomain-related regulatory mechanisms.
