MSCA 博士职位：基于结构的抗β-catenin新型多肽衍生物抑制剂设计

Georg August University Göttingen (Germany) Project Title: Structure-based design of novel peptide-derived β-catenin inhibitors Objectives: 1. Identify of hot spots in peptide binders. 2. Constrain the bioactive conformation to obtain high-affinity binders. 3. Identify peptidomimetics with the ability to inhibit Wnt signaling in cell-based assays. Project Overview: Using different peptide sequences as starting points truncation studies will be performed initially to identify the core binding region using fluorescence polarization assays as readout. Peptides will be obtained using solid-phase synthesis. The interaction of the most interesting candidates with β-catenin will be further characterized (e.g. via ITC), and structural elucidation of peptide/β-catenin complexes will be carried out by protein X-ray crystallography. Expression of the required β-catenin constructs is established. Core-peptide sequences will serve as the starting point for peptidomimetic design, employing intramolecular crosslinks to stabilize their bioactive confirmation. The resulting modified peptides, will be tested in cell-based reporter gene assays to assess their inhibitory effect on the Wnt signaling pathway. Best performing candidates will be further analyzed regarding their binding profile. Contribution to the overall research program: Provision of a set of specific and affinity-matured peptide binders to β-catenin. Skills and research profile: Experience with peptide or organic synthesis and the handling of proteins in biochemical assays. Salary: The position is funded by the Horizon Europe MSCA-DN project FlexCAT (Grant Agreement No. 101311592) for three years. The selected candidate will be offered a competitive salary comprising a Living Allowance (adjusted by the country correction coefficient), a Mobility Allowance, and, if applicable, a Family Allowance. All allowances are subject to applicable social security contributions and taxation. Planned secondment: Host: University of Sussex; Supervisor: Dr Rhys Morgan; Length: 3 months. Purpose: Testing cellular safety and toxicity.
