Details

EIF2AK3 (Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3), also known as PERK, is a metabolic-stress sensing protein kinase that phosphorylates and inactivates the alpha subunit of eukaryotic translation initiation factor 2 in response to various stress conditions. The action of EIF2AK3 directly results in a rapid reduction of translational initiation and protein synthesis. EIF2AK3 acts in response to various stress conditions such as low amino acid availability and misfolded proteins, and is thought to control mitochondrial morphology and function. Mutations in EIF2AK3 are associated with Wolcott-Rallison syndrome.
