The mouse Eif2ak4 antibody is designed to detect eukaryotic translation initiation factor 2 alpha kinase 4 (EIF2AK4), also known as general control nonderepressible 2 (GCN2), a critical enzyme in cellular stress response pathways. EIF2AK4/GCN2 is a serine/threonine kinase that senses amino acid deprivation and other stressors, activating the integrated stress response (ISR) by phosphorylating the alpha subunit of eukaryotic initiation factor 2 (eIF2α). This phosphorylation reduces global protein synthesis while selectively promoting the translation of stress-responsive genes, such as ATF4. to restore cellular homeostasis.
In mice, Eif2ak4 plays roles in metabolic regulation, immune responses, and neuronal function, with implications in diseases like cancer, neurodegeneration, and metabolic disorders. The antibody specifically targets mouse EIF2AK4. enabling researchers to study its expression, localization, and activation in tissues or cell lines under stress conditions. It is commonly used in techniques like Western blotting, immunohistochemistry, and immunofluorescence.
Validated in knockout controls, the antibody helps elucidate EIF2AK4’s structural domains, including its kinase and histidyl-tRNA synthetase-like regions, which are essential for binding uncharged tRNAs during amino acid starvation. Its application in preclinical models supports investigations into therapeutic strategies targeting the ISR pathway.
