A spatially and functionally distinct pool of TORC1 defines signaling endosomes in yeast

Hatakeyama, Riko ; De Virgilio, Claudio

In: Autophagy, 2019, vol. 15, no. 5, p. 915–916

The evolutionarily conserved target of rapamycin complex 1 (TORC1) regulates cell growth in a homeostatic manner by tuning anabolic and catabolic processes in response to nutritional and hormonal cues. Interestingly, rather than being localized at the plasma membrane as perhaps expected for an integrator of extracellular signals, TORC1 mainly localizes at vacuolar (in yeast) and lysosomal (in...

Spatially distinct pools of TORC1 balance protein homeostasis

Hatakeyama, Riko ; Péli-Gulli, Marie-Pierre ; Hu, Zehan ; Jaquenoud, Malika ; Osuna, Guillermo Miguel Garcia ; Sardu, Alessandro ; Dengjel, Jörn ; Virgilio, Claudio De

In: Molecular Cell, 2019, vol. 73, no. 2, p. 325-338.e8

The eukaryotic TORC1 kinase is a homeostatic controller of growth that integrates nutritional cues and mediates signals primarily from the surface of lysosomes or vacuoles. Amino acids activate TORC1 via the Rag GTPases that combine into structurally conserved multi-protein complexes such as the EGO complex (EGOC) in yeast. Here we show that Ego1, which mediates membrane-anchoring of EGOC via...
