Gating currents review
WebAug 1, 1999 · Rothberg and Magleby 1999 examined in detail the gating of single BK channels under a limited range of conditions: +30 mV, primarily at saturating [Ca 2+]. Horrigan et al. 1999 and Horrigan and Aldrich 1999 examined macroscopic ionic and gating currents (respectively), over a wide voltage range but in the effective absence of [Ca 2+]. Webactivation rate of Nav channels gating currents (Lacroix et al. 2013, 2014). These results strongly suggest that the physical structure and the underlying mechanism controlling the activation rate of voltage-gated ion channels involve the hydrophobic strength of the gating pore, especially of the residue at position 287. 1
