EIF2AK3 / PERK

eukaryotic translation initiation factor 2-alpha kinase 3

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. Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin-D1 (CCND1). Involved in control of mitochondrial morphology and function.

Gene Name: eukaryotic translation initiation factor 2-alpha kinase 3
Family/Subfamily: Protein Kinase , Translational Control Kinase
Synonyms: EIF2AK3, HRI, HsPEK, Pancreatic eIF2-alpha kinase, PEK, PERK, PKR-like ER kinase, WRS
Target Sequences: NM_004836 NP_004827.4 Q9NZJ5
