Proteins Critical to Cell Signaling Designed from Scratch

Proteins Critical to Cell Signaling Designed from Scratch

Working entirely from scratch, protein design researchers have now built simplified versions of calcium ion channels. These are tiny pores that generate electrical impulses on the membranes of excitable cells. The signals drive heartbeat, muscle contractions, and the release of chemical messages between nerve cells. Although biochemists have studied ion channels for decades, the debate about how...
