The identification of four acidic amino acids as potential calcium-binding residues in the TMEM16A calcium-activated chloride channel furthers the molecular understanding of this ion channel family.
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.
SOM+ GABAergic neuronal signaling and inhibitory transmission in the central lateral amygdala is regulated by TMEM16B, which is also involved in fear and anxiety-like behaviors.
A newly characterized calcium-activated chloride channel has been implicated in the immune system of Drosophila, shedding light on an enigmatic family of transmembrane proteins that are ubiquitous in nature.
An unbiased genome-wide human forward genetic screen identifies the vacuolar ATPase complex and assembly factors as regulators of HIF stability through their actions on intracellular iron metabolism.
Structures of the non-canonical potassium channel TMEM175 in open and closed states reveal unique mechanisms for channel gating and the selective permeation of K+ ions.
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.
The structural relationship between TMC and TMEM16 proteins provides insight into the structure and functional mechanisms of the mechanotransduction channel complex in hair cells.
Ion conduction in the calcium-activated chloride channel TMEM16A is directly regulated by calcium, which binds to a site close to the pore thereby shaping the electrostatics at its intracellular entrance.
