Tom1 Modulates Binding of Tollip to Phosphatidylinositol 3-Phosphate via a Coupled Folding and Binding Mechanism.
Early endosomes represent the first sorting station for vesicular ubiquitylated cargo. Tollip, through its C2 domain, associates with endosomal phosphatidylinositol 3-phosphate (PtdIns(3)P) and binds ubiquitylated cargo in these compartments via its C2 and CUE domains. Tom1, through its GAT domain, is recruited to endosomes by binding to the Tollip Tom1-binding domain (TBD) through an unknown m...
متن کاملFolding for binding or binding for folding?
A number of proteins are (partially) unstructured at physiological conditions and assume a well-defined three-dimensional structure only upon binding to another protein or macromolecular complex. Numerous examples have been found especially among proteins involved in regulatory functions in eukaryotic cells. Recent computer simulations by Verkhivker et al. have yielded an atomic detail picture ...
متن کاملLinking folding and binding.
Many cellular proteins are intrinsically disordered and undergo folding, in whole or in part, upon binding to their physiological targets. The past few years have seen an exponential increase in papers describing characterization of intrinsically disordered proteins, both free and bound to targets. Although NMR spectroscopy remains the favored tool, a number of new biophysical techniques are pr...
متن کاملInterplay between partner and ligand facilitates the folding and binding of an intrinsically disordered protein.
Protein-protein interactions are at the heart of regulatory and signaling processes in the cell. In many interactions, one or both proteins are disordered before association. However, this disorder in the unbound state does not prevent many of these proteins folding to a well-defined, ordered structure in the bound state. Here we examine a typical system, where a small disordered protein (PUMA,...
متن کاملCoupled folding-binding in a hydrophobic/polar protein model: impact of synergistic folding and disordered flanks.
Coupled folding-binding is central to the function of many intrinsically disordered proteins, yet not fully understood. With a continuous three-letter protein model, we explore the free-energy landscape of pairs of interacting sequences and how it is impacted by 1), variations in the binding mechanism; and 2), the addition of disordered flanks to the binding region. In particular, we focus on t...
