Tau Modifications Sections of NESTOR

In this work, we demonstrate that acute oxidative stress and mild heat stress (HS) induce the accumulation of dephosphorylated Tau in neuronal nuclei. Using chromatin immunoprecipitation assays, we demonstrate that the capacity of endogenous Tau to interact with neuronal DNA increased following HS. Comet assays performed on both wildtype and Tau-deficient neuronal cultures showed that Tau fully protected neuronal genomic DNA against HS-induced damage. Interestingly, HS-induced DNA damage observed in Tau-deficient cells was completely rescued after the overexpression of human Tau targeted to the nucleus. PubMed:21131359

This post-translational modification is likely an indicator of good health since its intracellular level correlates with the availability of extracellular glucose. From a more practical point of view, it has been shown that O-GlcNAcylation impairments contribute to the etiology of cardiovascular diseases, type-2 diabetes and Alzheimer's disease (AD), three illnesses common in occidental societies.

>8 phosphates per tau molecules (vs 2 in adult healthy brain); can also be increased during development, hibernation and temperature, heat and oxydative stress These phosphorylated states are detected by specific antibodies and are targets of proline-directed kinases (SP motifs), non-proline kinases (KXGS motif) Weakens tau-MT interaction especially S261 in R1 and S214 in proline-rich domain PubMed:8226987
