Protein
Eukaryotic translation initiation factor 2-alpha kinase
Organism
Drosophila melanogaster
Function
Phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2 (EIF2), leading to its inactivation and thus to a rapid reduction of translational initiation and repression of global protein synthesis.
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily.
