Scientific Background

EIF2AK3 (Eukaryotic Translation Initiation Factor 2-Alpha Kinase 3), also called PEK, is an enzyme that in humans is encoded by the EIF2AK3 gene. By fluorescence in situ hybridization and radiation hybrid analysis, Hayes et al. (1999) mapped the EIF2AK3 gene to chromosome 2p12.Harding et al. (2000) reported that a targeted mutation of the mouse Eif2ak3 gene, which they called Perk, abolished the phosphorylation of eIF2-alpha in response to accumulation of malfolded proteins in the ER, resulting in abnormally elevated protein synthesis and higher levels of ER stress. Using a library of endoribonuclease-prepared short interfering RNAs (esiRNAs), Kittler et al. (2004) identified 37 genes required for cell division, one of which was EIF2AK3.
