Helical Packing Regulates Structural Transitions In Bax, Nuska Tschammer

Electronic Theses and Dissertations

Apoptosis is essential for development and the maintenance of cellular homeostasis and is frequently dysregulated in disease states. Proteins of the BCL-2 family are key modulators of this process and are thus ideal therapeutic targets. In response to diverse apoptotic stimuli, the pro-apoptotic member of BCL-2 family, BAX, redistributes from the cytosol to the mitochondria or endoplasmic reticulum and primes cells for death. The structural changes that enable this lethal protein to transition from a cytosolic form to a membrane-bound form remain poorly understood. Elucidating this process is a necessary step in the development of BAX as a novel therapeutic ...
