PERK (eukaryotic translation initiation factor 2-A kinase 3, eIF2A kinase 3, PEK, WRS) is a Ser/Thr protein kinase, type I membrane protein of the endoplasmic reticulum that is abundant in secretory tissues and is inducible by ER-stress. PERK phosphorylates the A subunit of eukaryotic translation-initiation factor 2 (EIF2), leading to its inactivation, a reduction of translation initiation and repression of global protein synthesis. PERK may serve as an effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin D1. PERK dimerizes with HSPA5/BIP in resting cells and oligomerizes in ER-stressed cells. Perturbation in protein folding in the endoplasmic reticulum (ER) can promote dissociation from HSPA5/BIP and oligomerization, resulting in autophosphorylation and kinase activity induction.
