After a decade of debate, a clear picture of a controversial protein that helps regulate heart contractions

Brandeis University researchers have unlocked a controversial structure in heart cells responsible for regulating heart contractions.For years, scientists have debated how many KCNE1 proteins are required to build a potassium ion channel, theorizing anywhere between one and 14. Now, Brandeis University 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.
