We therefore phosphorylated full-length Tau by MARK2. The downfield chemical shift of phosphorylated residues (Fig. 4a) is in agreement with previous reports and confirms phosphorylation at S262, S293, S305, S324, S356, and S416 PubMed:29215007

While residues Ser-262, Ser-324, and Ser-356 were completely phosphorylated, Ser-293 in the second repeat was only 84% phosphorylated (Table 1). Furthermore, four non-KXGS phosphorylation sites were detected, two within the repeat domain (Ser-305 in R2 and Ser-352 in R4) and two more at the C-terminus (Ser-413 and Ser-416) (Figure 1B,C). Of these, Ser-305 was 66% phosphorylated and Ser-352, Ser-413, and Ser-416 were ∼45−58% phosphorylated (Table 1). Using wild-type MARK2cat at 25 °C and pH 6.8, the same phosphorylation sites were observed. The three primary sites, Ser-262, Ser-324, and Ser-356, were still completely phosphorylated.

The NMR experiments demonstrate that MARK2- phosphorylation of Tau attenuates its binding to F-actin. Consistent with a reduced affinity, MARK2-phosphorylated Tau failed in bundling actin filaments (Fig. 4e) PubMed:29215007

The lysine-isoleucine-glycineserine motif (KIGS) or lysine-cysteineglycine-serine motif (KCGS) motifs in the repeat domain (S262, S293, S324, S356) can be phosphorylated by MARK, PKA, SAD kinases, CaMKII and p70S6K, which strongly reduces the tau microtubule interactions (36, 74, 96), [note that phosphorylation at these sites also inhibits tau aggregation, illustrating an analogous role for the repeat domain in the physiological and pathological functions of tau (106)].
