Anti-PAIP2 antibodies are used in the immunodetection of the protein poly(A) binding protein interacting protein 2. In humans, the canonical protein has a reported length of 127 amino acid residues and a mass of 15 kDa. Its subcellular localization is in the cytoplasm. It is reported to be expressed at highest level in testis, but also abundant in the brain, cervix, lung, ovary, placenta, adipose tissue, thymus and thyroid. A member of the PAIP2 protein family, PAIP2 is known to act as a repressor in the regulation of translation initiation of poly(A)-containing mRNAs. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include polyadenylate-binding protein-interacting protein 2, PABC1-interacting protein 2, PABP-interacting protein 2, polyA-binding protein-interacting protein 2, and PAIP2A. PAIP2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. A number of PAIP2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
