Functioni

Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 (eIF-2-alpha/EIF2S1) on 'Ser-52' in response to low amino acid availability (PubMed:10504407, PubMed:10655230, PubMed:12176355, PubMed:12215525, PubMed:15213227, PubMed:16054071, PubMed:16176978, PubMed:16121183, PubMed:15774759, PubMed:16601681, PubMed:26102367). Plays a role as an activator of the integrated stress response (ISR) required for adapatation to amino acid starvation. Converts phosphorylated eIF-2-alpha/EIF2S1 either to a competitive inhibitor of the translation initiation factor eIF-2B, leading to a global protein synthesis repression, and thus to a reduced overall utilization of amino acids, or to a translational initiation activation of specific mRNAs, such as the transcriptional activator ATF4, and hence allowing ATF4-mediated reprogramming of amino acid biosynthetic gene expression to alleviate nutrient depletion (PubMed:10655230, PubMed:11106749, PubMed:12176355, PubMed:15213227, PubMed:16176978, PubMed:26102367). Binds uncharged tRNAs (By similarity). Involved in cell cycle arrest by promoting cyclin D1 mRNA translation repression after the unfolded protein response pathway (UPR) activation or cell cycle inhibitor CDKN1A/p21 mRNA translation activation in response to amino acid deprivation (PubMed:16176978, PubMed:26102367). Plays a role in the consolidation of synaptic plasticity, learning as well as formation of long-term memory (PubMed:16121183). Plays a role in neurite outgrowth inhibition (PubMed:23447528). Plays a role in feeding behavior to maintain amino acid homeostasis; contributes to the innate aversion toward diets of imbalanced amino acid composition (PubMed:16054071, PubMed:15774759). Plays a proapoptotic role in response to glucose deprivation (PubMed:20660158). Promotes global cellular protein synthesis repression in response to UV irradiation independently of the stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK) and p38 MAPK signaling pathways (PubMed:12176355).By similarity14 Publications
(Microbial infection) Plays a role in the antiviral response against alphavirus infection; impairs early viral mRNA translation of the incoming genomic virus RNA, thus preventing alphavirus replication (PubMed:16601681). Plays a role in modulating the adaptive immune response to yellow fever virus infection; promotes dendritic cells to initiate autophagy and antigene presentation to both CD4+ and CD8+ T-cells under amino acid starvation (PubMed:24310610).2 Publications

(Microbial infection) Kinase activity is enhanced by alphavirus genomic RNA sequences (PubMed:16601681). Kinase activity is stimulated upon binding to uncharged tRNAs (PubMed:16601681). Activated by serum starvation (in vitro) (PubMed:10504407).2 Publications

Pathology & Biotechi

Disruption phenotypei

Mice are viable, fertile, and exhibit no phenotypic abnormalities under standard growth conditions (PubMed:12215525). Show an increase in prenatal and neonatal mortalities when essential amino acids are absent in the maternal diet during gestation (PubMed:12215525, PubMed:15213227). In response to nutrient deprivation, display reduced abilities to chronically down-regulate hepatic protein synthesis, resulting in preservation of liver mass relative to body size and enhanced skeletal muscle loss (PubMed:15213227). Mice exhibit a lowered threshold for the induction of strong and robust long-term potentiation (LTP) in the CA1 neurons of the hippocampus and the consolidation of long-term memory (PubMed:16121183). Knockout and conditional knockout in the brain result in a diminution of the rate of food consumption and an impairment in the food aversion response in mice fed an imbalanced amino acid diet (PubMed:16054071). Mice are more susceptible to intranasal Sindbis virus infection, with high virus titers in the brain compared to similarly infected control animals (PubMed:16601681). Mice infected with yellow fever virus show a decrease in dendritic cell autophagy and an impairment in their capacity to present antigens to T-cells under amino acid starvation (PubMed:24310610).6 Publications

Interactioni

Subunit structurei

Homodimer; homodimerization is important for kinase activation by uncharged tRNAs (By similarity). Interacts with GCN1; this interaction stimulates EIF2AK4/GCN2 kinase activity and is impaired by IMPACT upon a variety of stress conditions, such as amino acid depletion, UV-C irradiation, proteasome inhibitor treatment and glucose deprivation (PubMed:24333428). Interacts with DNAJC3; this interaction inhibits EIF2AK4/GCN2 kinase activity during endoplasmic reticulum (ER), hypothermic and amino acid-starving stress conditions (PubMed:25329545).By similarity2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
