Fig. 1From: Critical residues involved in tau binding to fyn: implications for tau phosphorylation in Alzheimer’s diseasePXXP motifs in the proline-rich region of full-length human tau. The amino acid sequence of the longest isoform of human CNS tau is shown, with the PXXP motifs underlined and numbered (1–7). Individual proline to alanine substitutions within the PXXP motifs are indicated by asterisksBack to article page
