Intrinsically disordered regions of proteins often mediate important protein-protein interactions. However, the folding-upon-binding nature of many polypeptide-protein interactions limits the ability of modeling tools to predict the three-dimensional structures of such complexes. To address this problem, we have taken a tandem approach combining NMR chemical shift data and molecular simulations to determine the structures of peptide-protein complexes. Here, we use the MELD (Modeling Employing...
[NMR paper] Combining NMR, SAXS and SANS to characterize the structure and dynamics of protein complexes
Combining NMR, SAXS and SANS to characterize the structure and dynamics of protein complexes
Understanding the structure and dynamics of biological macromolecules is essential to decipher the molecular mechanisms that underlie cellular functions. The description of structure and conformational dynamics often requires the integration of complementary techniques. In this review, we highlight the utility of combining nuclear magnetic resonance (NMR) spectroscopy with small angle scattering (SAS) to characterize these challenging biomolecular systems. NMR can assess the structure and...

[NMR paper] Structural model of the human BTG2-PABPC1 complex by combining mutagenesis, NMR chemical shift perturbation data and molecular docking
Structural model of the human BTG2-PABPC1 complex by combining mutagenesis, NMR chemical shift perturbation data and molecular docking
Degradation of cytoplasmic mRNA in eukaryotes involves the shortening and removal of the mRNA poly(A) tail by poly(A)-selective ribonuclease (deadenylase) enzymes. In human cells, BTG2 can stimulate deadenylation of poly(A) bound by cytoplasmic poly(A)-binding protein PABPC1. This involves the concurrent binding by BTG2 of PABPC1 and the Caf1/CNOT7 nuclease subunit of the Ccr4-Not deadenylase complex. To understand in molecular detail how PABPC1 and BTG2...

Combining NMR ensembles and molecular dynamics simulations provides more realistic models of protein structures in solution and leads to better chemical shift prediction
Abstract While chemical shifts are invaluable for obtaining structural information from proteins, they also offer one of the rare ways to obtain information about protein dynamics. A necessary tool in transforming chemical shifts into structural and dynamic information is chemical shift prediction. In our previous work we developed a method for 4D prediction of protein 1H chemical shifts in which molecular motions, the...
