WebJan 19, 2024 · Various post translational modifications like hyper phosphorylation, O-GlycNAcylation, and acetylation have been attributed to induce the abnormal folding in tau protein. Recent in vitro studies revealed the possible involvement of N–glycosylation of tau protein in the abnormal folding and tau aggregation. Hence in this study, we performed … WebFeb 1, 2024 · Four PPIases have been implicated in tau biology. FKBP51 and 52 regulate the turnover of native tau protein, which affects the levels of tau in neurons ( 4, 13 ). FKBP12 and Pin1 are PPIases that directly regulate tau misfolding by regulating proline isomerization in the central microtubule-interacting region.
