Jefferson scientists uncover new clues to how crucial molecular gatekeepers work

One of the biggest mysteries in molecular biology is exactly how ion channels – tiny protein pores through which molecules such as calcium and potassium flow in and out of cells – operate. Such channels can be extremely important; members of the voltage-gated ion channel family are crucial to generating electrical pulses in the brain and heart, carrying signals in nerves and muscles.
