Structural basis for activation of voltage sensor domains in an ion channel TPC1

Kintzer AF, Green EM, Dominik PK, Bridges M, Armache JP, Deneka D, Kim SS, Hubbell W, Kossiakoff AA, Cheng Y, Stroud RM

Proc. Natl. Acad. Sci. U.S.A. 2018 Sep;

PMID: 30190435

Abstract

Voltage-sensing domains (VSDs) couple changes in transmembrane electrical potential to conformational changes that regulate ion conductance through a central channel. Positively charged amino …
