| Full Name | eukaryotic translation initiation factor 2 alpha kinase 4 |
| Alias | GCN2, PVOD2 |
| Introduction | Phosphorylation of the alpha subunit of eukaryotic initiation factor 2 is a well-documented mechanism of downregulating protein synthesis under a variety of stress conditions. Kinases activated by viral infection (PKR), endoplasmic reticulum stress (PERK/PEK), amino acid deprivation (GCN2) and hemin deficiency (HRI) can phosphorylate the alpha subunit of eIF2. GCN2 is also required for UV-light induced translation inhibition, and in vivo phosphorylation of murine GCN2 at Thr898 is induced by both UV irradiation and by leucine deprivation. UV-induced activation of NF-kappaB also requires GCN2, which may act simply by preventing translation of IkappaB-alpha to replace pools that have been ubiquitinated and degraded. Interestingly, proteasome inhibitors (MG132 and ALLN) activate the GCN2/eIF2alpha pathway, suggesting a pivotal role for this kinase in stress response and ubiquitin-mediated signaling. In vitro autophosphorylation of yeast GCN2 within its activation loop at Thr882 and Thr887 (Thr898 and Thr903 in mouse) has also been reported. |
