Anti-exosome component 3 antibodies are used for the immunodetection of the protein encoded by the EXOSC3 gene. In humans, the canonical protein has a reported length of 275 amino acid residues and a mass of 29.6 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the RRP40 protein family, it is reported to be a non-catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. Other names for this target antigen include PCH1B, RRP40, Rrp40p, bA3J10.7, hRrp-40, p10, exosome complex component RRP40, and CGI-102. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of exosome component 3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
