Functioni

Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 (eIF-2-alpha/SUI2) on 'Ser-52' in response to low amino acid availability (PubMed:1739968, PubMed:7623840, PubMed:8798780, PubMed:9528799, PubMed:10983975, PubMed:17202131). Plays a role as an activator of the general amino acid control (GAAC) pathway required for adapatation to amino acid starvation. Converts phosphorylated eIF-2-alpha/SUI2 either to a competitive inhibitor of 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 GCN4, and hence allowing GCN4-mediated reprogramming of amino acid biosynthetic gene expression to alleviate nutrient depletion (PubMed:2660141, PubMed:2188100, PubMed:1739968, PubMed:7621831, PubMed:7623840, PubMed:8798780, PubMed:10801780, PubMed:11350982, PubMed:24333428). Binds uncharged tRNAs (PubMed:7623840, PubMed:10983975).13 Publications
(orthologuous-specific) Binds to aminoacylated tRNA(Phe) less tightly than to deacylated tRNA(Phe) (PubMed:10983975). Binds to double-stranded RNA (PubMed:9430731).2 Publications

Interactioni

Subunit structurei

Homodimer; homodimerization is important for kinase activation by uncharged tRNAs (PubMed:9566889, PubMed:10983975, PubMed:11250908, PubMed:17202131, PubMed:15964839). Interacts (via N-terminal RWD domain) with GCN1 (via N- and C-terminus); this interaction stimulates GCN2 kinase activity in a GCN20-dependent manner in response to amino acid starvation (PubMed:10775272, PubMed:11101534, PubMed:10801780, PubMed:11350982, PubMed:21849502). Interacts (via N-terminus) with the GCN1-GCN20 complex on translating ribosomes in amino acid-starved cells; GCN1 may bind near the ribosomal A-site and promotes the transfer of uncharged tRNAs from the A-site to the tRNA-binding domain in GCN2 for its subsequent kinase activation, and hence allowing GCN4 translational activation and derepression of amino acid biosynthetic genes (PubMed:10775272, PubMed:11101534). Interacts (via C-terminus) with TIF11; this interaction is direct, occurs in amino acid-repleted cells, may be stabilzed in a ribosome-dependent manner, reduces GCN2-mediated eIF-2-alpha phosphorylation but not GCN2 autophosphorylation and is lost in amino acid-starved cells and by uncharged tRNAs (PubMed:21849502). Associates (via C-terminus) with ribosomes (PubMed:2038314, PubMed:9430731, PubMed:10983975, PubMed:22888004).13 Publications

Domaini

The C-terminal domain negatively regulates kinase activity via an autoinhibitory association with the protein kinase and histidyl-tRNA synthetase-like domains in amino acid-repleted cells, that is counteracted by uncharged tRNAs in amino acid-starved cells (PubMed:7623840, PubMed:8798780, PubMed:10983975, PubMed:11250908). The C-terminal, histidyl-tRNA synthetase-like region and protein kinase domains are necessary for homodimer formation (PubMed:9566889, PubMed:10983975, PubMed:11250908). The C-terminal and protein kinase domains are necessary for ribosome association (PubMed:9566889, PubMed:10983975). The C-terminal and histidyl-tRNA synthetase-like regions are required for uncharged tRNAs binding in amino acid-starved cells (PubMed:7623840, PubMed:8798780, PubMed:9430731, PubMed:10983975).6 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.
