EIF2AK1 (HRI) Human Protein

Back to top


EIF2AK1 (HRI) is one of 4 kinases that specifically phosphorylate Ser51 of translation initiation factor eIF2-alpha in response to various environmental stresses, leading to a decrease in protein sythesis. In the case of EIF2AK1, signaling is initiated by low levels of heme.
