mTOR Signaling in 4R-Tauopathies

🔬 Protein Info
Gene Symbolent-gene-7b80a607
Function- ULK1 inhibition: Persistent mTORC1 activity blocks ULK1 complex activation
ULK1 inhibitionPersistent mTORC1 activity blocks ULK1 complex activation
TFEB mislocalizationmTOR phosphorylates TFEB, preventing nuclear translocation
Lysosomal dysfunctionReduced lysosomal biogenesis impairs tau clearance
Regional specificitymTOR dysregulation is most severe in globus pallidus and substantia nigra
Asymmetric presentationmTOR activity often higher in more affected hemisphere
Neuronal loss correlationmTOR hyperactivity correlates with neuronal loss in affected cortices
Astrocytic involvementReactive astrocytes show mTOR activation
TFEB nuclear exclusionSimilar to PSP, TFEB is retained in cytoplasm
DatabasesGeneCardsUniProtNCBI GeneHPASTRING
