Activating transcription factor 4 (ATF4) is 351 amino acid basic leucine zipper (bZIP) stress-responsive transcription factor that belongs to the cAMP response element-binding protein 2 (CREB 2) family of proteins. The protein contains a leucine zipper domain that is responsible for the formation of homo and heterodimers necessary for protein-protein interactions. ATF4 is stimulated under cellular stress conditions such as amino acid depletion by General Control Nonderepressible-2 (GCN2) and protein kinase R-like ER kinase (PERK). Both GCN2 and PERK phosphorylate eIF2α and inhibit global protein translation. However, phosphorylation of eIF2α stimulates ATF4 to switch on nonessential amino acid (NEAA) biosynthesis and promote transportation activity of amino acids to help cells cope with amino acid depletion. ATF4 plays a role in the differentiation of osteoblasts and may provide insights into the progression of skeletal diseases. ATF4 also plays a significant role in diseases such as diabetic retinopathy, Alzheimer’s, Parkinson’s, Huntington’s, and prion disease. BioVision’s ATF4 (Human) ELISA kit quantitatively measures ATF4 in human serum, plasma, and other biological fluids. Test samples, Standards, and Biotinylated Detection antibody are added to the wells pre-coated with capture antibody and then washed with Wash Buffer. HRP-Streptavidin is added to the plate, and post-incubation any unattached conjugates are washed off by Wash Buffer. The HRP enzymatic reaction is detected using TMB-substrate. Finally, an acidic stop solution terminates the enzymatic reaction. The color developed is directly proportional to the amount of ATF4 in the sample or standard.
