Abstract

Chen, Malia, Hatakeyama, et al. demonstrate that the yeast Target of Rapamycin Complex 1 (TORC1) phosphorylates the lipid kinase Fab1, a homolog of metazoan PIKfyve. Fab1 phosphorylation shifts both complexes from the vacuole to signaling endosomes and changes TORC1 activity, suggesting a regulatory feedback loop in cellular signaling from these organelles.
