Descriptions

Biochem/physiol Actions

Eukaryotic translation initiation factor 2-? kinase 1 (EIF2AK1) modulates protein synthesis. It acts at the level of translation initiation to downregulate protein synthesis in response to stress. The protein is activated by heme deficiency and other stimuli and is a major protein kinase that phosphorylates EIF2-?. EIF2AK1 is downregulated in the majority of ovarian cancers compared with normal ovarian tissues. It functions in iron homeostasis and may play a role in hemolytic and inflammatory anemia.

General description

Eukaryotic translation initiation factor 2-? kinase 1 (EIF2AK1) or HRI is a kinase that can be inactivated by hemin. The gene encoding this protein is localized on human chromosome 7p22.1.
