New molecular map reveals how cells spew out potassium

New molecular map reveals how cells spew out potassiumResearchers have determined for the first time the complete structure of an ion channel known as BK, or “big potassium.” This molecular map offers new insights on how BK works and may aid in the development of treatments for diseases in which it malfunctions.

Hardworking sodium/ potassium pump fundamentally similar to free-flowing ion channel

Right now, in your body, tiny pumps in the fatty membranes surrounding all your cells are hard at work pushing select charged ions, such as sodium, potassium or calcium, through those membranes. Like a water pump in a high-rise apartment building overcoming the force of gravity to move water up to a tank on its roof, these ion pumps work against “electrochemical gradients” to transport ions from one side of the membrane to the other.
