FREDERICK, Md. -- A study defining how an oncogenic protein gets removed from its active spot may offer new ways to target unwanted cell growth, a hallmark of cancer.

KRAS is a membrane-binding protein that functions as a molecular switch to regulate cellular activity, and is the most frequently mutated oncogene in human cancer. Normal KRAS controls cell growth. When KRAS is mutated, the signal is disrupted and cells grow continuously.
