The Fas receptor is a representative death receptor, and the Fas-associated protein with death domain (FADD) is a crucial adapter protein needed to support the Fas receptor’s activity. The Fas–FADD interactions constitute an important signaling pathway that ultimately induces apoptosis or programmed cell death in biological systems. The interactions responsible for this cell-death process are governed by the binding process of the Fas ligand to the Fas, followed by the caspase cascade activation. Using a computational approach, the present communication explores certain essential structural aspects of the Fas–FADD death domains and their interfacial interactions.
