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)].

a(CHEBI:"transfer RNA") increases bp(GO:"neurofibrillary tangle assembly") View Subject | View Object

As noticed earler, it is difficult to obtain PHFs from constructs containing domains outside the repeats or the second repeat, at least under conditions where assembly is driven by high ionic strength and high protein concentration [5,26]. This would suggest that some non-repeat domains of tau prevent PHF formation. The same tendency is observed here again, but low we find that the inhibition can be easily overcome by RNA in most cases. Since dimers are building blocks of PHFs, the extra repeat (no. 2) effectively acted as a PHF inhibitor [22]. However, this inhibition can be overcome by tRNA. PubMed:8985176

In the present study we injected bilaterally 3-morpholino-sydnonimine (SIN-1), a recognized and widely used peroxynitrite donor (25–30), into rat hippocampus, and investigated whether or not peroxynitrite could induce simultaneously nitration and hyperphosphorylation of tau and the underlying mechanisms in vivo. The level of nitrated and hyperphosphorylated tau was markedly increased in rat hippocampus 24 h, and prevented by preinjection of uric acid, a natural scavenger of peroxynitrite. GSK-3beta and p38 MAPKs, including p38alpha, p38beta, and p38delta activity was increased, but no change in the activity of p38gamma, ERK, and c-Jun amino-terminal kinase (JNK). Both nitrated tau and hyperphosphorylated tau were aggregated in the hippocampus, with activity of 20S proteasome significantly arrested in SIN-1-injected rats. Hyperphosphorylated tau was degraded as efficiently as normal tau by 20S proteasome, but the nitrated tau with an unorderly secondary structure became more resistant to the proteolysis, providing evidence that peroxynitrite simultaneously induces tau hyperphosphorylation, nitration, and accumulation, and that activation of GSK-3beta, p38alpha, p38beta, p38delta isoforms and the inhibition of proteasome activity are respectively responsible for the peroxynitrite-induced tau hyperphosphorylation and accumulation.

Tau-nY29 detects soluble tau and paired helical filament tau from severely affected Alzheimer's brain but fails to recognize tau from normal aged brain. This observation suggests that nitration at Tyr29 is a disease-related event that may alter the intrinsic ability of tau to self-polymerize. In Alzheimer's brain, Tau-nY29 labels the fibrillar triad of tau lesions, including neurofibrillary tangles, neuritic plaques, and, to a lesser extent, neuropil threads. Intriguingly, although Tau-nY29 stains both the neuronal and glial tau pathology of Pick disease, it detects only the neuronal pathology in corticobasal degeneration and progressive supranuclear palsy without labeling the predominant glial pathology.
