Regulation of K(+) Flow by a Ring of Negative Charges in the Outer Pore of BK(Ca) Channels. Part I: Aspartate 292 modulates K(+) Conduction by External Surface Charge Effect

The pore region of the majority of K(+) channels contains the highly conserved GYGD sequence, known as the K(+) channel signature sequence, where the GYG is critical for K(+) selectivity (Heginbotham, L., T. Abramson, and R. MacKinnon. 1992. Science. 258:1152–1155). Exchanging the aspartate residue...
