Genetic information | Eif2ak4_GCN2-deficient gene (GCN2 allele constitutively missing exon XII (GCN2). Exon XII encodes a region of GCN2 that binds ATP, and its deletion eliminates kinase activity. |
Phenotypic information | Homozygous:GCN2 homozygous mutant mice exhibit a less aversive response towards imbalanced diet, therefore eIF2 kinase GCN2 has an important role in mediating aversion toward foods with an imbalanced amino acid composition. GCN2-induced eIF2 phosphorylation may promote the aversive response through its effects on translation and transcription in cells of the Anterior Piriform Cortex (APC), in other brain regions, and in other peripheral organs.Heterozygous:GCN2 heterozygous mutant mice, exhibit a wild-type aversive response toward foods with an imbalanced amino acid composition. |
