ERI1 (Exoribonuclease 1): ERI1 is a key enzyme involved in RNA interference and the regulation of small RNA stability. It plays a vital role in degrading RNA duplexes and resolving RNA-induced silencing complexes (RISCs), which are essential for gene silencing. ERI1’s function impacts gene expression and cellular defense against viruses. Research on ERI1 explores its role in post-transcriptional regulation and its potential significance in antiviral responses and cancer.
