About the Project
The overall goal of the project is the isolation of peptide modulators of RAS signalling pathway. The project encompass with two main tasks: firstly, computational design of peptides; and secondly, experimental validation of the predictions. The computational design of peptide modulators will be carried out using “in house” developed software as well as common tools used in protein design. The second part of the project would be the experimental validation (in vitro) of the predictions, i.e. whether peptides would bind to RAS and block interactions with partners. To that end, the RAS-AntiRAS antibody protein complex (Tanaka et al. 2007) will be used. On a first approach, SPR assays will be used to assess the binding of peptides to RAS. Further characterization would include NMR data, pull-down, and competition assays among other experimental tools.
The candidate will develop his/her research tasks in both a computer-based (dry-lab) and experimental lab (wet-lab). Thus, it will suit a candidate willing to work both with computers and in an experimental lab setting. Although desirable, programming skills are not essential, however training will be provided as required.
