NCIt definition : Eukaryotic translation initiation factor 2-alpha kinase 1 (630 aa, 71 kDa) is encoded
by the human EIF2AK1 gene. This protein plays a role in both the inhibition of protein
synthesis and serine/threonine phosphorylation.;
NCIt note : The enzymatic activity of eukaryotic translation initiation factor 2-alpha kinase
1 protein is regulated by heme levels. The presence of heme inhibits the activity
of this protein whereas low heme levels cause induction of activity.;
