General description
Eukaryotic translation initiation factor 2-α kinase 4 (EIF2AK4), also known as GCN2 is an enzyme encoded by EIF2AK4 gene in humans. In mouse, EIF2AK4 is widely expressed with prominent expression in liver and brain.
Biochem/physiol Actions
Eukaryotic translation initiation factor 2-α kinase 4 (EIF2AK4) is responsible for phosphorylation of the a subunit of the eukaryotic initiation factor 2 (eIF2α). The EIF2AK4 eIF2-α kinase regulates fatty-acid homeostasis in the liver during deprivation of an essential amino acid. The protein p58IPK inhibits EIF2AK4 activity. EIF2AK4 is linked to pulmonary veno-occlusive disease (PVOD) development and its pathway is associated with diseases such as cancer and Alzheimer′s disease. The protein affects many aspects of cellular physiology in response to a number of stresses such as starvation. Mutation in EIF2AK4 may cause autosomal-recessive pulmonary capillary hemangiomatosis (PCH). EIF2AK4 causes tumor growth and angiogenesis by expression of vascular endothelial growth factor (VEGF).
