    Taken together, human high-grade gliomas increase TELO2 mRNA expression, and overexpression of TELO2 mRNA expression correlates with shorter survival outcome, supporting that TELO2 is an oncotarget in human gliomas.

    Overexpression of TELO2 decreases survival in human high-grade gliomas.

    IP7, formed by IP6K2, binds CK2 to enhance its phosphorylation of the Tti1/Tel2 complex, thereby stabilizing DNA-PKcs and ATM. This process stimulates p53 phosphorylation at serine 15 to activate the cell death program.

    Inositol pyrophosphates mediate the DNA-PK/ATM-p53 cell death pathway by regulating CK2 phosphorylation of Tti1/Tel2.

    Data show that that knockdown of either Tti1 or Tel2 causes disassembly of mTORC1 and mTORC2.

    The CK2 phospho-dependent interaction between TEL2 and the R2TP complex affects phosphatidylinositol 3-kinase-related kinase functions and is essential for mTOR and SMG1 stability in vivo.

    CK2 phospho-dependent binding of R2TP complex to TEL2 is essential for mTOR and SMG1 stability.

    TTI1 and TTI2 exist in multiple complexes, including a 2-MDa complex with TEL2 (telomere maintenance 2), called the Triple T complex, and phosphoinositide-3-kinase-related protein kinases (PIKKs) such as ataxia telangiectasia-mutated (ATM).

    A genetic screen identifies the Triple T complex required for DNA damage signaling and ATM and ATR stability.
