Cancer chain in cell membrane seen with supercomputers

Supercomputer simulations reveal clusters of a protein linked to cancer warp cell membranes -- findings could help design new anticancer drugs. Researchers used XSEDE/TACC supercomputers Lonestar and Stampede to simulate molecular dynamics of Ras protein clusters at the cell membrane. Simulations give greater understanding of Ras protein role in cancer and provide models for further experimental tests.
