Protons in gating the Kv1,2 channel: a calculated conformational change in response to addition of a proton, and a proposed path from voltage sensing domain to gate

The paper presents a quantum calculation of protonation changes in the Kv1.2 channel's S4-S5 linker and proposes proton pathways linking voltage sensing to gating.

The Role of Ion Transition from the Pore Cavity to the Selectivity Filter in the Mechanism of Selectivity and Rectification in the Kv1.2 Potassium Channel: Transfer of Ion Solvation from Cavity Water to the Protein and Water of the Selectivity Filter

This paper uses quantum calculations to show how threonine residues in the Kv1.2 potassium channel enable selectivity and rectification by facilitating ion transfer from the cavity to the selectivity filter through a ratchet and pawl mechanism.

K+ in a Kv1.2 Channel Pore: Hydration, Selectivity, and the Role of a Conserved Threonine

The paper uses quantum calculations to show how K+ ions pass through a Kv1.2 channel and how the channel selectively allows K+ over Na+ by trapping Na+ with threonine -OH groups.

The Role of Proton Transport in Gating Current in a Voltage Gated Ion Channel, as Shown by Quantum Calculations

The paper challenges the traditional model of voltage-gated ion channel gating by proposing that proton motion, not arginine charge displacement, primarily contributes to gating current, supported by quantum calculations on the Kv1.2 channel.
