EIF2AK3
Human protein and coding gene From Wikipedia, the free encyclopedia
Remove ads
Eukaryotic translation initiation factor 2-alpha kinase 3, also known as protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK), is an enzyme that in humans is encoded by the EIF2AK3 gene.[5][6][7][8]

Function
The protein encoded by this gene 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. It is a type I membrane protein located in the endoplasmic reticulum (ER), where it is induced by ER stress caused by malfolded proteins.[6]
Clinical significance
Patients with mutations in this gene develop Wolcott-Rallison syndrome.[9]
Interactions
EIF2AK3 has been shown to interact with DNAJC3,[10] NFE2L2,[11] and endoplasmic reticulum chaperone BiP (Hsp70).[12]
