COPENHAGEN, Denmark, June 29 (UPI) — Researchers have discovered the protein that allows the enzyme ADAM17 to remove molecules from the surface of cancer cells, helping them to grow.
The protein PACS-2 helps ADAM17 transport into and out of the cell. However, if the protein is blocked, the enzyme returns to the cell surface less often, meaning it can’t help cells to grow.
