Gene name:
EIF2AK3 (PEK;PERK) ;
Protein name:
Eukaryotic translation initiation factor 2-alpha kinase 3 ;
Alternative:
Pancreatic eIF2-alpha kinase (HsPEK) ;PRKR-like endoplasmic reticulum kinase ;
Organism:
Human (Homo sapiens).
General Annotation
Sub Unit:
Forms dimers with HSPA5/BIP in resting cells. Oligomerizes in ER-stressed cells. Interacts with DNAJC3.
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. Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin D1.
Subcellular Location:
Endoplasmic reticulum membrane
Single-pass type I membrane protein
