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 ...

Potassium channels are essential membrane proteins that enable the selective and rapid transport of K⁺ ions, a process fundamental to cellular excitability and signal transduction. Recent research has ...

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 ...

Voltage-gated potassium (Kv) channels play an important role in modulating the electrical activity of cells, opening in response to changes in membrane voltage and allowing potassium ions to escape.

This article and associated images are based on a poster originally authored by Sivakumar, M, Smith, E, Shumate, J, Scampavia, L, Spicer, T, Hernandez, D and Peters, C and presented at ELRIG Drug ...

A mechanism involving potassium channels in the brain that control brain cell activity could provide a new and fundamentally different way of treating depression symptoms in adults with major ...

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 ...

Researchers find blocking the KCNB2 gene can slow tumor growth, paving the way for next-gen treatments for childhood brain cancer. Scientists at The Hospital for Sick Children (SickKids) have ...

A study published in the 19 October Nature shows that one subunit of a potassium channel has a pivotal role in controlling vascular smooth muscle tone. This raises the possibility that defects in this ...
