These EIF4E1 ELISA kits are immunodetection tools for measuring the levels of EIF4E1 in biological samples. EIF4E1 is an alias name of the human EIF4E gene, which encodes the protein, eukaryotic translation initiation factor 4E. Notably, EIF4E1 is known to play a role in the differentiation of certain cell types, among other functions. The EIF4E protein is 217 amino acid residues in length and 25.1 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. This protein is known to be phosphorylated. Other names for this target antigen include AUTS19 and CBP.
