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.
Cryo-EM structures of the gating cycle of bestrophin reveal the molecular underpinnings of activation and inactivation gating in this calcium-activated chloride channel and reveal a surprisingly wide pore.
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.
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.
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.
A functional link between representative family members of the CLCA channel regulator family and TMEM16 channels suggests that these protein families may cooperate in influencing multiple homeostatic and disease physiologies.
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 multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca2+-dependent Cl- current in human RPE.
Research into light-gated ion channels called channelrhodospins laid the foundations for the development of optogenetics, a technique that has gone on to revolutionize neuroscience.
