Pho85, Kcs1 and Vip1 contribute to tau phosphorylation by different kinases. Native wild-type tau (N) and the clinical R406W tau mutant (Vanhelmont et al., 2010) were expressed in wild-type (wt), pho85, kcs1, and vip1 strains, and the electrophoretic profile of the protein from logarithmic-SCD-Ura-grown (Abs600 ∼0.3) cells was analyzed by Western blot using Tau5 and phospho-specific antibodies against S396/S404 (AD2) and S409 (PG5) epitopes. The graphs show the AD2 and PG5 band intensities (±SD) expressed as arbitrary units. Protein extraction, band intensity determination, and statistical analysis were as described in Figure 1C. Data are the mean (±SD) of three independent experiments. *p < 0.05 for AD2 or PG5 band intensity of the mutant strains compared with AD2 or PG5 band intensity of the wild-type control strain. Representative Western blots images are shown.
