... of tau with Fyn-SH3. We also show that tau interacts with the SH2 domain of Fyn, and that this associa- tion, unlike that of Fyn-SH3, is influenced by Fyn-mediated tyrosine phos- phorylation of ... SH3 domain of Fyn binds to proline-rich motifs within the sequence PXXP in interacting pro- teins. Seven such motifs are present in the proline-rich domain of the longest isoform of ta...
