Protein systems make up the complex signaling pathways that control whether a cell divides or, in some cases, metastasizes. Ras proteins have long been the focus of cancer research because of their role as ‘on/off switch’ signaling pathways that control cell division and failure to die like healthy cells do.
Now, a team of researchers has been able to study precisely how Ras proteins interact with cell membrane surfaces. Read more . . .
