SCF(FBXO9) recognizes and binds mTORC1-bound TTI1 and TELO2 when they are phosphorylated by CK2 following growth factor deprivation, leading to their degradation. In contrast, the SCF(FBXO9) does not mediate ubiquitination of TTI1 and TELO2 when they are part of the mTORC2 complex. As a consequence, mTORC1 is inactivated to restrain cell growth and protein translation, while mTORC2 is activated due to the relief of feedback inhibition by mTORC1. {ECO:0000269|PubMed:23263282}. |F-box-like| |F-box| |SCF ubiquitin ligase complex| |SCF-dependent proteasomal ubiquitin-dependent protein catabolic process| |regulation of TOR signaling| |ubiquitin ligase complex| |fat cell differentiation| |ubiquitin-protein transferase activity| |protein polyubiquitination| |proteasome-mediated ubiquitin-dependent protein catabolic process| |proteasomal protein catabolic process| |post-translational protein modification| |ubiquitin-dependent protein catabolic process| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |cellular protein catabolic process| |protein catabolic process| |protein ubiquitination| |innate immune response| |protein modification by small protein conjugation| |cellular macromolecule catabolic process| |defense response to other organism| |protein modification by small protein conjugation or removal| |macromolecule catabolic process| |organonitrogen compound catabolic process| |proteolysis| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |organic substance catabolic process| |cellular catabolic process| |regulation of intracellular signal transduction| |immune response| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp19|Etoposide 1μM R00 exp19]]|1.76| No correlation found to any other genes in chemogenomics.
