In a surprising new finding, neuroscientists have shown that human neurons have a much lower density of ion channels than expected, compared to the neurons of other mammals. Ion channels produce ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a 'ball-and-chain' channel-plugging mechanism. The findings boost the ...

Potassium channels can become nonconducting via inactivation at a gate inside the highly conserved selectivity filter (SF) region near the extracellular side of the membrane. In certain ligand-gated ...
