Researchers have discovered a new mechanism for potassium channel inhibitor entry, which could improve the specificity of drugs targeting the channel. Upon binding to calcium ions, BK channels allow ...
Following this design principle, the researchers create angstrom-scale pores in bi-layer graphene sheets, and decorate the two pore edges with twisted rings of carbonyl groups. The artificial ion ...
Molecular dynamics simulations show how potassium passes through an ion channel at atomic resolution
They are literally channels for communication: Pore-forming proteins in living cells, termed ion channels, are embedded in the outer membrane of almost all cell types and play a crucial role in the ...
Potassium channels are openings that allow charged potassium atoms to cross the cell membrane. Voltage-gated potassium channels — which open only when a specific voltage is reached across the cell ...
Proceedings of the National Academy of Sciences of the United States of America, Vol. 119, No. 9 (March 1, 2022), pp. 1-10 (10 pages) Voltage-gated ion channels confer excitability to biological ...
Underlying every thought, heartbeat and movement are ion channels, busily conducting high-speed streams of ions into cells, like subway trains coursing through tunnels. Ion channels span the cellular ...
