Project A04 – Characterizing the molecular interaction between the Y receptor and arrestin
We aim at providing structural data on the active complex of Y receptors with arrestin as well as information on the modification of the equilibrium dynamics of the receptor. To achieve this, we will (i) combine peptide synthesis and protein ligation techniques to prepare NMR-active proteins with a few isolated isotopic labels and EPR-active proteins. (ii) We will use solution and solid-state NMR techniques to determine the backbone structure of segments of arrestin in interaction with Y receptors. (iii) We will determine structural constraints to determine the mutual orientation and will verify this with mutagenesis of both, arrestin and Y receptors. (iv) We will investigate the molecular dynamics of the Y receptors in response to agonist and arrestin binding as well as dynamic alterations in response to conformational changes arrestin undergoes upon binding to the receptor.
