Abstract
The Fas antigen, a cell surface receptor belonging to the tumor necrosis factor receptor(TNFR) superfamily, triggers programmed cell death (apoptosis) in the immune system. Thethree-dimensional structure of Fas and molecular details of the interaction between Fas andits ligand are currently unknown. A three-dimensional model of the Fas extracellular regionwas generated by comparative modeling. Inverse folding analysis suggested goodsequence–structure compatibility of the model and thus reasonable accuracy. Themodel was analyzed in the light of information provided by studies on TNFR and CD40,another member of the TNFR family, and the Fas ligand binding site was predicted.
