CC -!- FUNCTION: Acts as a positive activator of the GCN2 protein kinase
CC activity in response to amino acid starvation (PubMed:15937339). Forms
CC a complex with EIF2AK4/GCN2 on translating ribosomes; during this
CC process, GCN1 seems to act as a chaperone to facilitate delivery of
CC uncharged tRNAs that enter the A site of ribosomes to the tRNA-binding
CC domain of EIF2AK4/GCN2, and hence stimulating EIF2AK4/GCN2 kinase
CC activity (By similarity). Participates in the repression of global
CC protein synthesis and in gene-specific mRNA translation activation,
CC such as the transcriptional activator ATF4, by promoting the
CC EIF2AK4/GCN2-mediated phosphorylation of eukaryotic translation
CC initiation factor 2 (eIF-2-alpha/EIF2S1) on 'Ser-52', and hence
CC allowing ATF4-mediated reprogramming of amino acid biosynthetic gene
CC expression to alleviate nutrient depletion (PubMed:24333428).
CC {ECO:0000250|UniProtKB:P33892, ECO:0000269|PubMed:15937339,
CC ECO:0000269|PubMed:24333428}.
CC -!- SUBUNIT: Interacts with EIF2AK4/GCN2; this interaction stimulates the
CC EIF2AK4/GCN2 kinase activity and is impaired by IMPACT upon a variety
CC of stress conditions, such as amino acid depletion, UV-C irradiation,
CC proteasome inhibitor treatment and glucose deprivation
CC (PubMed:24333428). Interacts with IMPACT; this prevents the interaction
CC of GCN1 with EIF2AK4/GCN2 and inhibits EIF2AK4/GCN2 kinase activity
CC (PubMed:15937339, PubMed:22404850). {ECO:0000269|PubMed:15937339,
CC ECO:0000269|PubMed:22404850, ECO:0000269|PubMed:24333428}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305|PubMed:23447528}.
CC Note=Associates with ribosomes in undifferentiated neuroblastoma cells
CC and increases after neuronal differentiation (PubMed:23447528).
CC -!- TISSUE SPECIFICITY: Expressed in the hypothalamus, cortex and
CC hippocampus (PubMed:15937339). {ECO:0000269|PubMed:15937339}.
CC -!- SIMILARITY: Belongs to the GCN1 family. {ECO:0000305}.
