A molecular switch to better understand signaling

In the alphabets of our genomes, a single typo can mean the difference between health and disease. The "words" are molecules, like enzymes, and one group of these called kinases are particularly important. However, it's difficult to pick apart the exact roles of misspellings in various kinases in a disease process. This week in ACS Central Science, researchers report development of a new way to determine this, both in a lab dish and in mice.
