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 ...

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 ...

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 ...

Researchers have identified a crucial ion channel, TMEM175, that acts like an overflow valve in the cell’s recycling system.

Researchers from The University of Osaka find that potassium KCNQ2/3 channels, which are important for suppressing brain cell ...

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.

Potassium KCNQ2/3 channels are crucial for suppressing the excitability of brain cells, or neurons. When these channels don't work properly, they can cause specific types of epilepsy like benign ...

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 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 ...
