Anti-EIF4E1B antibodies are used in the immunodetection of the protein eukaryotic translation initiation factor 4E family member 1B. In humans, the canonical protein has a reported length of 242 amino acid residues and a mass of 27.6 kDa. It is notably expressed in the cerebellum. A member of the Eukaryotic initiation factor 4E protein family, Eif4e1b is known to recognize and bind the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structure. Synonyms for this target antigen include eukaryotic translation initiation factor 4E type 1B. EIF4E1B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is a widely used application for the Eif4e1b antibodies listed below. In addition, Immunohistochemistry is also a common application.
