General description

The protein named 3'-5' exoribonuclease 1 or 3′-5′ exonuclease ERI1, Eri-1 homolog, Histone mRNA 3′-end-specific exoribonuclease, Histone mRNA 3′-exonuclease 1, or Protein 3′hExo (HEXO), and encoded by the human gene ERI1/ 3'EXO,/THEX1 is an 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. Eri1 also can degrade 3' overhangs on short interfering RNAs (siRNAs) suggestion a possible wider role in RNA interference, and finally Eri1 also processes other RNAs, including ribosomal RNAs and Eri1 is part of a pre-mRNA processing complex and can bind ribosomal subunits and assembled ribosomes too. Recent research also has identified Eri1 as a regulator of micro RNA and plays a role in miRNA homeostasis, lymphocyte development and antiviral functions. Eri1 is localized to the cytoplasm and nucleus, as well as, the nucleolus in normal cells.
