While activated by a common mechanism, both functions in TMEM16F - lipid scrambling and ion conduction - are likely mediated by alternate protein conformations that are at equilibrium in the ligand-bound state.
Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.
A concerted approach employing equilibrium and biased molecular simulations, electrophysiology, mutagenesis, and functional assays reveals, in atomic details, the mechanism and pathway for transport of phospholipids and ions by a lipid scramblase.
Single-particle cryo-EM and electrophysiology studies of the chloride channel TMEM16A reveals the structural basis for anion conduction and uncover its relationship to lipid scramblases of the same family.
Genetic and molecular analyses show that FOXC1 and FOXC2 play a role in controlling lymphatic valve maintenance as key mediators of mechanotransduction to control cytoskeletal organization and RhoA/ROCK signaling.
