Overview
GCN2 a kinase of the PEK family. Phosphorylates and inhibits eukaryotic initiation factor (eIF)-2 alpha, providing an important protective mechanism during various cellular stress conditions including endoplasmic reticulum (ER) stress. Note: This description may include information from UniProtKB.
Protein type: Translation; Protein kinase, Ser/Thr (non-receptor); EC 2.7.11.1; Kinase, protein; Protein kinase, Other; Other group; PEK family; GCN2 subfamily
Molecular Function: protein serine/threonine kinase activity; protein homodimerization activity; ATP binding; eukaryotic translation initiation factor 2alpha kinase activity
Biological Process: regulation of translation initiation in response to stress; unfolded protein response; negative regulation of translation; cellular response to starvation; protein amino acid phosphorylation; regulation of translational initiation
Reference #:  Q9P2K8 (UniProtKB)
Alt. Names/Synonyms: E2AK4; EIF2AK4; eukaryotic translation initiation factor 2 alpha kinase 4; Eukaryotic translation initiation factor 2-alpha kinase 4; GCN2; GCN2 eIF2alpha kinase; GCN2-like protein; KIAA1338
Gene Symbols: EIF2AK4
Molecular weight: 186,911 Da
Basal Isoelectric point: 5.88  Predict pI for various phosphorylation states
