      Ras GTPase-activating protein-binding proteins 1 and 2 (G3BP1 and G3BP2, respectively) are widely recognized as core components of stress granules (SGs). We report that G3BPs reside at the cytoplasmic surface of lysosomes. They act in a non-redundant manner to anchor the tuberous sclerosis complex (TSC) protein complex to lysosomes and suppress activation of the metabolic master regulator mechanistic ...

    • The PI3K and MAPK/p38 pathways control stress granule assembly in a hierarchical manner 

      Heberle, Alexander Martin; Razquin Navas, Patricia; Langelaar-Makkinje, Miriam; Kasack, Katharina; Sadik, Ahmed; Faessler, Erik; Hahn, Udo; Marx-Stoelting, Philip; Opitz, Christiane A.; Sers, Christine; Heiland, Ines; Schaeuble, Sascha; Thedieck, Kathrin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-28)
      All cells and organisms exhibit stress-coping mechanisms to ensure survival. Cytoplasmic protein-RNA assemblies termed stress granules are increasingly recognized to promote cellular survival under stress. Thus, they might represent tumor vulnerabilities that are currently poorly explored. The translation-inhibitory eIF2α kinases are established as main drivers of stress granule assembly. Using a ...

    • Upregulation of tryptophanyl-tRNA synthethase adapts human cancer cells to nutritional stress caused by tryptophan degradation 

      Adam, Isabell; Dewi, Dyah L.; Mooiweer, Joram; Sadik, Ahmed; Mohapatra, Soumya R.; Berdel, Bianca; Keil, Melanie; Sonner, Jana K.; Thedieck, Kathrin; Rose, Adam J.; Platten, Michael; Heiland, Ines; Trump, Saskia; Opitz, Christiane A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-05)
      Tryptophan (Trp) metabolism is an important target in immuno-oncology as it represents a powerful immunosuppressive mechanism hijacked by tumors for protection against immune destruction. However, it remains unclear how tumor cells can proliferate while degrading the essential amino acid Trp. Trp is incorporated into proteins after it is attached to its tRNA by tryptophanyl-tRNA synthestases. As ...
