_4 value "{From full text} For example, phosphorylation of eIF2{alpha} by GCN2 (EIF2AK4) is enhanced by amino acid limitation, UV irradiation, and proteasome inhibition (13?16). Phosphorylation of eIF2{alpha} inhibits general protein synthesis by reducing the levels of eIF2-GTP that are required for binding of initiator tRNA to the translation apparatus. Concomitant with lowered protein synthesis, eIF2{alpha} phosphorylation leads to preferential translation of ATF4, a basic zipper (bZIP) transcription activator important for directing transcription of stress-related genes (17?20). Reduced protein synthesis conserves energy and provides the cell time for ATF4 and other stress-responsive transcription factors to reconfigure gene expression slated to alleviate damage elicited by the underlying stress. Other members of the eIF2 kinase family include PEK/Perk (EIF2AK3), whose activity is enhanced by endoplasmic reticulum (ER) stress (21, 22); HRI (EIF2AK1), which is regulated by heme deficiency and oxidative stress (23); and PKR (EIF2AK2), which functions in an antiviral pathway (24).{P@S52 is the common phosphorylation site between all 4 kinases and confirmed in Uniprot}" provenance.
