CALCIUM-DEPENDENT ELECTROSTATIC CONTROL OF ANION ACCESS TO THE PORE OF THE CALCIUM-ACTIVATED CHLORIDE CHANNEL TMEM16A

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

TMEM16A is a ligand-gated anion channel that is activated by intracellular Ca2+.This channel comprises two independent pores and closely apposed Ca2+ binding sites that are contained within each subunit Sugar Bowls of a homodimeric protein.Previously we characterized the influence of positively charged pore-lining residues on anion conduction (Paul
