WitrynaA single-point mutation (Pro 475→Asp) at the internal entrance of the low-conductance Shaker K-channel increases unitary currents by 6–8-fold (Sukhareva et al., 2003), which we proposed arose from increased pore occupancy due to the electronegative surface that mutation creates (Moscoso et al., 2012). Such a dramatic increase on the ...
