PERK, also named as EIF2AK3 and PEK, belongs to the protein kinase superfamily, Ser/Thr protein kinase family and GCN2 subfamily. PERK 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. PERK serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin D1. It catalyzes the reaction: ATP + a protein = ADP + a phosphoprotein. Defects in EIF2AK3 are the cause of Wolcott-Rallison syndrome (WRS). The antibody is specific to PERK.
