KirBac channels are prokaryotic homologs of mammalian inwardly rectifying (Kir) potassium channels, and recent crystal structures of both Kir and KirBac channels have provided major insight into their ...

Voltage-dependent potassium channels (Kv) are homotetramers composed of four voltage sensors and one pore domain. Because of high-level structural flexibility, the first mammalian Kv structure, Kv1.2 ...

Potassium channels are critical structures in biology; they selectively allow potassium ions to pass through the membrane surrounding cells. The precise gating of that channel is essential to its ...

The structure of potassium ion channels that regulate contractions in the heart has been illuminated by research. For years, scientists have debated how many KCNE1 proteins are required to build a ...

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 ...

In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in ...

Do only potassium ions pass through the selectivity filter of a potassium channel, or are there water molecules between the ions? This question has been a source of controversy for years. Researchers ...
