Recently, it has been proposed that bestrophins are Cl-channels and that the putative second transmembrane domain participates in forming the bestrophin pore. However, the structural determinants of Cl-ion permeation through the channel pore are not known. Here we systematically replaced every amino acid in mouse bestrophin-2 (mBest2) between positions 69 and 104 with cysteine. We then measured the effects on the relative permeability and conductance of the channel to Cl- and SCN-(thiocyanate) and determined the accessibility of the cysteine-substituted amino acids to extracellularly applied, membrane-impermeant sulfhydryl reagents. Unlike K+ channels, the amino acids forming the mBest2 selectivity filter are not discretely localized but are distributed over approximately 20 amino acids within the transmembrane domain. Cysteine-substituted amino acids in the selectivity filter are easily accessible to extracellularly applied sulfhydryl reagents and select for anionic sulfhydryl reagents over cationic ones. Understanding the structure of the anion conduction pathway of bestrophins provides insights into how mutations produce channel dysfunction and may provide important information for development of therapeutic strategies for treating macular degeneration."xsd:string |
