...Lyssa T. Gold; Glenn R. Masson GCN2 (general control nonderepessible 2) is an eIF2α kinase responsible for entirely rewiring the metabolism of cells when they are put under amino acid starvation stress. Recently, there has been renewed interest in GCN2 as a potential oncotarget, with several...

... apoptosis during periods of stress. Central to the ISR is the protein kinase General Control Non-depressible 2 (GCN2), which is responsible for sensing starvation. Upon amino acid deficiency, GCN2 is activated and initiates the ISR by phosphorylating the translation initiation factor eIF2α, stalling protein...

...Beáta Grallert; Erik Boye Gcn2 was first described in budding yeast as a serine/threonine protein kinase involved in the response to amino acid starvation and this is its best characterized role to date. Recent work has revealed new and exciting roles for Gcn2, which affect many aspects of cellular...
