Scientists develop 3-D model of regulator protein bax

Scientists at Freie Universität Berlin, the University of Tubingen, and the Swiss Federal Institute of Technology in Zurich (ETH) provide a new 3D model of the protein Bax, a key regulator of cell death. When active, Bax forms pores in the membranes of mitochondria, causing the release of proteins from the intermembrane space into the cytoplasm. This in turn triggers a series of operations ending in cell death, which are often impaired in cancer cells.
