VEGF165 (lacking exon 6 but not 7) has some heparin-binding affinity and so upon secretion exists in equilibrium between soluble and cell-associated forms.
The Affinity Clamping concept exploits the potential of nonhomologous recombination of protein domains in generating large changes in protein function and the inherent binding affinity and specificity of the so-called modular interaction domains toward short peptide motifs.
Computational models rationalize the binding affinity and the inhibition mechanism.
The binding affinity and molecular conformations are discussed.
11C-SU11274 has the same structure as SU11274, and therefore, its binding affinity and specificity was preserved.
Their multiligand chelation ability enhances their binding affinity and stability.
Recognition helix (RH) substitutions change DNA-binding affinity and specificity.
The difference of ability of Th17 induction between two peptides may come from MHC-binding affinity and TCR-binding affinity.
Among the cases we studied, the F− ion has the strongest binding affinity with SMC, so the channel needs the highest pressure to overcome the energy barrier to open the channel.
Presumably such peptide residues with few intermolecular interactions contribute relative little to the overall peptide-MHC binding affinity so that such docking errors do not dramatically reduce binding affinity prediction performance.
However, fragment hits typically possess high 'ligand efficiency' (binding affinity per heavy atom) and so are highly suitable for optimization into clinical candidates with good drug-like properties.
