Anti-PAIP2B antibodies are used in the immunodetection of the protein poly(A) binding protein interacting protein 2B. In humans, the canonical protein has a reported length of 123 amino acid residues and a mass of 14.2 kDa. It is reported to be expressed in the brain, cervix, heart, liver, ovary, kidney, prostate and testis. A member of the PAIP2 protein family, PAIP2B is reported to inhibit translation of capped and polyadenylated mRNAs by displacing PABPC1 from the poly(A) tail. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include polyadenylate-binding protein-interacting protein 2B and PABP-interacting protein 2B. PAIP2B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Immunocytochemistry is a widely used application for the PAIP2B antibodies listed below. In addition, Immunofluorescence is also a common application.
