Mtorc1 and s6k phosphorylation
Did you know?
WebIt binds with the FK506-binding protein 12 (FKBP12), which then directly binds mTORC1 and obscures the correct alignment of substrates to its catalytic cleft, thus preferentially inhibiting phosphorylation of the mTOR substrate p70 ribosomal protein S6 kinase (S6K) over 4E-binding protein 1 (4EBP1). 21 In all three cell lines, temsirolimus ... Web27 sept. 2016 · Our phosphoproteomics data suggest that mTORC1 and S6K are key nodes in FGF21 signaling. The mTORC1 substrate and activation site of S6K1 (S444/427) was the third most highly phosphorylated kinase activation site (4.5- and 2.6-fold change at 5 min) after ERK2 T183/Y185 (13.7- and 8.0-fold change at 5 min) and FGFR1 Y653/Y654 (9.2 …
WebActive mTORC1 gets recruited to the scaffold, and once there, will phosphorylate S6K to make it active. mTORC1 phosphorylates S6K1 on at least two residues, with the most … Web11 ian. 2024 · Thus, the phosphorylation of S6K in monocytes treated with 30 μM zinc and 5 mM 2-DG was comparable with that in monocytes treated with 3 μM zinc without 2-DG. Our data suggest that intracellular zinc is critical for mTORC1-S6K activation in human monocytes and macrophages and that zinc-mediated mTORC1 activity enhances …

Activation of both mTORC1 and mTORC2 could lead to upregulation of protein translation via the mTORC1-mediated S6K activation and the mTORC2-mediated Akt activation . These data strongly indicate a common shared function of mTOR at the …
Web21 aug. 2015 · We observed that sustained mTORC1 disruption persistently blocked S6K phosphorylation, but increased phosphorylation of Akt S473 ~2.5 fold and its down stream target, FOXO1/3 S319, compared to control (Fig 1F and 1G). Conversely, mTORC2 disruption markedly lowered Akt S473 phosphorylation compared to control .
