Caption

This image depicts the structure of the BAX protein (purple). The activator compound BTSA1 (orange) has bound to the active site of BAX (green), changing the shape of the BAX molecule at several points (shown in yellow, magenta and cyan). BAX, once in its final activated form, can home in on mitochondria and puncture their outer membranes, triggering apoptosis (cell death).
