Anti-3'hExo antibodies enable researchers to detect and measure the 3'hExo antigen in biological samples. This target is a reported synonym of the ERI1 gene, which encodes exoribonuclease 1. This protein is reported to be a RNA exonuclease that binds to the 3'-end of histone mRNAs and degrades them, suggesting that it plays an essential role in histone mRNA decay after replication. The human version of 3'hExo has a canonical amino acid length of 349 residues and a protein mass of 40.1 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. Indicated applications for 3'hExo antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
