pH-induced conformational changes in the selectivity filter of a potassium channel lead to alterations in its selectivity and permeation properties
The Selectivity Filter (SF) in tetrameric K+ channels, has a highly conserved sequence, TVGYG, at the extracellular entry to the channel pore region. There, the backbone carbonyl oxygens from the SF residues, create a stack of K+ binding sites where dehydrated K+ binds to induce a conductive conform...
