Researchers are using powerful supercomputers to figure out a mechanism that causes cell variations in most of the skin cancer cases. Researchers are hopeful their study can help lead to a better understanding of skin cancer and the design of better drugs. Researchers used cryo-electron microscopy to study the structure of this important protein called B-Raf. The study reveals an asymmetric structure of the complex, formed by pairs of bonded molecules. However, there is a lot to be discovered about B-Raf. Researchers are hopeful their study can help lead to a better study of skin cancer and the development of better drugs.
