  • Title: Identification of the ligand binding site in Fas (CD95) and analysis of Fas-ligand interactions.
    Author: Bajorath J.
    Journal: Proteins; 1999 Jun 01; 35(4):475-82. PubMed ID: 10382675.
    Abstract:
    Fas (CD95), a member of the tumor necrosis factor receptor superfamily, and its ligand (FasL), a tumor necrosis factor-like protein, are intensely studied because their interaction on the cell surface is critical for the induction of programmed cell death (apoptosis) and the regulation of immune responses. The structure and specificity of the extracellular binding domains of Fas and its ligand were studied, in different laboratories, by combining molecular modeling, mutagenesis, and a variety of binding and functional experiments. Residues critical for the receptor-ligand interaction were identified and, in the absence of experimentally determined structures, binding sites and details of the Fas-ligand interactions were predicted. These studies provide an instructive example for the close combination of prediction and experiment and illustrate how insights into the structure and binding characteristics of Fas and its ligand were gradually refined. Discussed methodological aspects are representative of structure-function studies on extracellular domains of other single-path transmembrane proteins.
