Title: Calculation of binding affinities of phosphopeptides towards 14-3-3ζ that are important in
neurobiochemistry of the brain.
Project Description
14-3-3 proteins play key role in the neurobiochemistry of brain and are also associated with neurodegenerative
amyloid diseases such as Alzheimer and Parkinson disease. 14-3-3 proteins bind more than 850 diverse target
phosphoproteins, thereby forcing conformational changes or/and stabilizing active conformations in their target
proteins. However, the preparation of high quantities of phosphorylated samples in high concentrations, needed for
experimental measurement of binding affinities, is usually very difficult. Therefore, this task will be addressed by the
accurate free energy calculations that represent an attractive alternative to the highly demanding experimental
determination of the binding affinities.
The main aim of this post-doctoral project is the calculation of binding affinities of phosphorylated peptides in the
complex with 14-3-3. Different schemes of Hamiltonian replica exchange molecular dynamics (H-REMD) will be
applied to a set of phosphopeptides bound to 14-3-3 and calculate their absolute binding affinities. The binding
affinities obtained from the potential of mean force of small peptides binding to 14-3-3 will be compared to
experimental binding affinities measured by ITC and NMR titration experiments.
Desired expertise and skills
Suitable candidates should have strong background in biomolecular simulations. Experience in enhanced sampling
techniques and free energy calculations are considered an asset.
