Global Phosphoproteomics Pinpoints Uncharted Gcn2-Mediated Modes of Translational Control


ABSTRACT: To identify new Gcn2 target proteins, we performed a set of Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC)-based quantitative phosphoproteomics experiments, in which we compared WT cells to gcn2∆ and sui2S52A cells (n=3), all treated, or not, with rapamycin, which has previously been shown to stimulate eIF2alpha phosphorylation by Gcn2.

The conserved Gcn2 protein kinase mediates cellular adaptations to amino acid limitation through translational control of gene expression that is exclusively executed by phosphorylation of the α-subunit of the eukaryotic translation initiation factor 2 (eIF2α). Using quantitative phosphoproteomics, however, we discovered that Gcn2 targets auxiliary effectors to modulate translation. Accordingly, Gcn2 also phosphorylates the β-subunit of the trimeric eIF2 G protein complex to promote its associat  ...[more]
