Anti-CPEB2 antibodies are used in the immunodetection of the protein cytoplasmic polyadenylation element binding protein 2. In humans, the canonical protein has a reported length of 589 amino acid residues and a mass of 64.9 kDa. Its subcellular localization is in the cytoplasm. Up to 8 different isoforms have been reported for this protein. A member of the RRM CPEB protein family, CPEB2 is believed to play a role in translational regulation of stored mRNAs in transcriptionally inactive haploid spermatids. Synonyms for this target antigen include CPE-binding protein 2. CPEB2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CPEB2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
