Disrupted coupling of gating charge displacement to Na(+) current activation for DIIS4 mutations in hypokalemic periodic paralysis

Missense mutations at arginine residues in the S4 voltage-sensor domains of Na(V)1.4 are an established cause of hypokalemic periodic paralysis, an inherited disorder of skeletal muscle involving recurrent episodes of weakness in conjunction with low serum K(+). Expression studies in oocytes have re...
