[NMR paper] Determination of intracellular protein-ligand binding affinity by competition binding in-cell NMR
Determination of intracellular protein-ligand binding affinity by competition binding in-cell NMR
Structure-based drug development suffers from high attrition rates due to the poor activity of lead compounds in cellular and animal models caused by low cell penetrance, off-target binding or changes in the conformation of the target protein in the cellular environment. The latter two effects cause a change in the apparent binding affinity of the compound, which is indirectly assessed by cellular activity assays. To date, direct measurement of the intracellular binding affinity remains a...

[NMR paper] Solution NMR of Nanoparticles in Serum: Protein Competition Influences Binding Thermodynamics and Kinetics
Solution NMR of Nanoparticles in Serum: Protein Competition Influences Binding Thermodynamics and Kinetics
The spontaneous formation of a protein corona on a nanoparticle surface influences the physiological success or failure of the synthetic nanoparticle as a drug carrier or imaging agent used in vivo. A quantitative understanding of protein-nanoparticle interactions is therefore critical for the development of nanoparticle-based therapeutics. In this perspective, we briefly discuss the challenges and limitations of current approaches used for studying protein-nanoparticle binding in a...

Pairwise binding competition experiments for sorting hub-protein/effector interaction hierarchy and simultaneous equilibria
Pairwise binding competition experiments for sorting hub-protein/effector interaction hierarchy and simultaneous equilibria
Abstract
NMR experiments on proteins in simultaneous equilibria with multiple binding partners can provide a tool to understand complex biological interaction networks. Competition among proteins for binding to signaling hubs is often at the basis of the information transmission across signaling networks in every organism. Changes in affinity towards one or more partners, as well as changes of the relative concentration of the...

Solution structure, dynamics and thermodynamics of the three SH3 domains of CD2AP
Solution structure, dynamics and thermodynamics of the three SH3 domains of CD2AP
Abstract CD2 associated protein (CD2AP) is an adaptor protein that plays an important role in cell to cell union needed for the kidney function. It contains three N-terminal SH3 domains that are able to interact among others with CD2, ALIX, c-Cbl and Ubiquitin. To understand the role of the individual SH3 domains of this adaptor protein we have performed a complete structural, thermodynamic and dynamic characterization of the separate domains using NMR and DSC. The energetic contributions to the stability...
