Stabilization of ion selectivity filter by pore loop ion pairs in an inwardly rectifying potassium channel

Ion selectivity is critical for the biological functions of voltage-dependent cation channels and is achieved by specific ion binding to a pore region called the selectivity filter. In voltage-gated K(+), Na(+) and Ca(2+) channels, the selectivity filter is formed by a short polypeptide loop (called...
