title: Proline-directed random-coil chemical shift values as a tool for the NMR assignment of the tau phosphorylation sites.
abstract: NMR spectroscopy of the full-length neuronal Tau protein has proved to be difficult due to the length of the protein and the unfavorable amino acid composition. We show that the random-coil chemical shift values and their dependence on the presence of a proline residue in the (i+1) position can successfully be exploited to assign all proline-directed phosphorylation sites. This is a first step toward the study of the phosphorylation of Tau by NMR spectroscopy.
