Anti-IGF2BP3 antibodies are used in the immunodetection of the protein insulin like growth factor 2 mRNA binding protein 3. In humans, the canonical protein has a reported length of 579 amino acid residues and a mass of 63.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in fetal liver, fetal lung, fetal kidney, fetal thymus, fetal placenta, fetal follicles of ovary and gonocytes of testis, growing oocytes, spermatogonia and semen. A member of the RRM IMP/VICKZ protein family, IGF2BP3 is reported to be an RNA-binding factor that may recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). Synonyms for this target antigen include CT98 and IMP-3. IGF2BP3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 90 citations in the literature describe the use of IGF2BP3 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
