Functional Implications of Glycogen Synthase Kinase-3-Mediated Tau Phosphorylation
Tau is primarily a neuronal microtubule-associated protein that has functions related to the stabilisation of microtubules. Phosphorylation of tau is an important dynamic and regulatory element involved in the binding of tau to tubulin. Thus, highly phosphorylated tau is more likely to be present in the cytosolic compartment of neurons, whereas reduced phosphate burden allows tau to bind to and...
متن کاملPhosphorylation of tau by glycogen synthase kinase 3beta affects the ability of tau to promote microtubule self-assembly.
To study the effects of phosphorylation by glycogen synthase kinase-3beta (GSK-3beta) on the ability of the microtubule-associated protein tau to promote microtubule self-assembly, tau isoform 1 (foetal tau) and three mutant forms of this tau isoform were investigated. The three mutant forms of tau had the following serine residues, known to be phosphorylated by GSK-3, replaced with alanine res...
متن کاملGlycogen synthase kinase-3β2 has lower phosphorylation activity to tau than glycogen synthase kinase-3β1.
Glycogen synthase kinase-3β (GSK-3β) is a serine/threonine kinase that phosphorylate protein substrates involved in Alzheimer's disease (AD), such as microtubule-associated protein tau and amyloid precursor protein (APP). GSK-3β consists of two splice variants; the major short form (GSK-3β1) distributes in many organs and the minor long form (GSK-3β2), whose structural difference is the insert ...
متن کاملValproate reduces tau phosphorylation via cyclin-dependent kinase 5 and glycogen synthase kinase 3 signaling pathways.
Valproate (VPA) is a widely used anticonvulsant and mood-stabilizing drug. Recent studies have shown that VPA could reduce amyloid-β generation, and improve memory deficits in transgenic mouse models of Alzheimer's disease (AD). However, whether VPA affects tau phosphorylation and the underlying mechanism has not been established. Here, we showed that systemic treatment of APP and presenilin 1 ...
متن کاملGlycogen synthase kinase-3β may contribute to neuroprotective effects of Sargassum oligocystum against amyloid-beta in neuronal SH-SY5Y cells
Glycogen synthase kinase (GSK)-3β mediates amyloid-beta (Aβ) and oxidative stress-induced neurotoxicity in neurodegenerative disorders. Natural products with antioxidant activity, such as Sargassum (S.) oligocystum may modulate GSK-3β enzyme and protect against Aβ-induced neurotoxicity. Therefore, we aimed to assess the neuroprotective effects of a methanolic extract of S. oligocystum against A...
