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 potassium ion channel, theorizing anywhere between one and 14. Now, researchers found that these channels are built with two E1s. Understanding the construction of this channel is key to understanding life-threatening heart conditions, such as arrhythmias, and developing drugs to threat those conditions.
