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 ...

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.

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 ...

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 ...

Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...

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 single mutation in a gene, Kcnc3, which encodes a potassium channel in neurons, causes learning deficits in mice, UT Southwestern researchers report in a new study in PNAS. The novel mutation ...

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 ...
