Functional Mapping of the Trpv1 Intracellular Binding Site

NMR mapping of the IFNAR1-EC binding site on IFNalpha2 reveals allosteric changes in the IFNAR2-EC binding site.

All type I interferons (IFNs) bind to a common cell-surface receptor consisting of two subunits. IFNs initiate intracellular signal transduction cascades by simultaneous interaction with the extracellular domains of its receptor subunits, IFNAR1 and IFNAR2. In this study, we mapped the surface of IFNalpha2 interacting with the extracellular domain of IFNAR1 (IFNAR1-EC) by following changes in o...

Exploring the Binding Site Structure of the PPARγ Ligand-Binding Domain by Computational Solvent Mapping†

Solvent mapping moves molecular probes, small organic molecules containing various functional groups, around the protein surface, finds favorable positions, clusters the conformations, and ranks the clusters based on the average free energy. Using at least six different solvents as probes, the probes cluster in major pockets of the functional site, providing detailed and reliable information on...

Mapping of drebrin binding site on F-actin.

Drebrin is a filament-binding protein involved in organizing the dendritic pool of actin. Previous in vivo studies identified the actin-binding domain of drebrin (DrABD), which causes the same rearrangements in the cytoskeleton as the full-length protein. Site-directed mutagenesis, electron microscopic reconstruction, and chemical cross-linking combined with mass spectrometry analysis were empl...
