Project A03 – Characterizing the molecular interactions of Y1 and Y2 receptors with NPY

In the proposed project, distance constraints of complexes between Y1 and Y2 receptors and NPY will be derived by NMR, using the paramagnetic relaxation enhancement (PRE) effect, as well as (photo-) chemical cross-linking combined with mass spectrometry (MS). The experimentally obtained constraints will be used to refine computational models of the NPY in the Y1 and the Y2 binding pocket. The ultimate goal is to characterize the binding modes and dynamics of peptides in interaction with Y receptors, which is a prerequisite for the development of highly selective drugs.
