Regulation of K+ flow by a ring of negative charges in the outer pore of BKCa channels. Part II: Neutralization of aspartate 292 reduces long channel openings and gating current slow component.
Haug T, Olcese R, Toro L, Stefani E. Haug T, et al. Among authors: stefani e. J Gen Physiol. 2004 Aug;124(2):185-97. doi: 10.1085/jgp.200308950. J Gen Physiol. 2004. PMID: 15277579 Free PMC article.
Neutralization of the aspartate near the selectivity filter in the GYGD pore sequence (D292N) of the voltage- and Ca(2+)-activated K+ channel (MaxiK, BKCa) does not prevent conduction like the corresponding mutation in Shaker channel, but profoundly affects major biophysical prop …

Correlation between charge movement and ionic current during slow inactivation in Shaker K+ channels.
Olcese R, Latorre R, Toro L, Bezanilla F, Stefani E. Olcese R, et al. Among authors: stefani e. J Gen Physiol. 1997 Nov;110(5):579-89. doi: 10.1085/jgp.110.5.579. J Gen Physiol. 1997. PMID: 9348329 Free PMC article.
The data could be fitted to a sequential model for Shaker K+ channels (Bezanilla, F., E. Perozo, and E. Stefani. 1994. Biophys. J. 66:1011-1021), with the addition of a series of parallel nonconducting (inactivated) states that become populated during prolong …
