Ion channels in organelles
Web13 apr. 2024 · Many membrane proteins including ion channels and ion transporters are regulated by membrane phospholipids such as phosphoinositides in cell membranes and organelles. Voltage-sensing phosphatase, VSP, is a voltage-sensitive phosphoinositide phosphatase which dephosphorylates PI(4,5)P2 into PI(4)P. VSP rapidly reduces the … WebThe Gordon Research Conference on Organellar Channels and Transporters, held for the 3rd time in 2024, is dedicated to ion channels and primary or secondary transporters from intracellular organelles in animals, plants, and yeasts.
