    Calcium-dependent electrostatic control of anion access to the pore of the calcium-activated chloride channel TMEM16A

    Andy KM Lam, Raimund Dutzler
    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.
