TLDR
It is demonstrated that phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) is a critical upstream modulator of TORC1 activity in yeast and is required forTORC1-dependent regulation of autophagy and nutrient-dependent endocytosis.
Abstract
The protein kinase TORC1 regulates cell growth in response to nutrients. This study demonstrates that phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) is a critical upstream modulator of TORC1 activity in yeast. In this capacity, PI(3,5)P2 is required for TORC1-dependent regulation of autophagy and nutrient-dependent endocytosis.
