**Background of EIF2B4 Antibody**
EIF2B4 (Eukaryotic Translation Initiation Factor 2B Subunit 4) is a critical component of the eukaryotic translation initiation factor 2B (eIF2B) complex, which regulates protein synthesis by catalyzing the exchange of GDP for GTP on eIF2. a key step in initiating mRNA translation. The eIF2B complex consists of five subunits (α–ε), with EIF2B4 (ε subunit) playing a structural and regulatory role. Mutations in *EIF2B4* or other subunits are linked to leukoencephalopathies, such as vanishing white matter disease (VWM), a fatal neurodegenerative disorder.
EIF2B4 antibodies are immunological tools designed to detect and quantify the ε subunit of the eIF2B complex. These antibodies are widely used in research to study eIF2B’s function in cellular stress responses, translation regulation, and disease mechanisms. For example, they help investigate how eIF2B dysfunction under stress (e.g., phosphorylation during the integrated stress response) impacts global protein synthesis.
In diagnostics, EIF2B4 antibodies aid in identifying pathogenic mutations or altered expression in VWM patients. Their applications include Western blotting, immunohistochemistry, and immunofluorescence to localize the protein in tissues or cultured cells. Research using these antibodies has advanced understanding of eIF2B’s role in neurological health and disease, offering insights into potential therapeutic targets for disorders associated with translational dysregulation.
