Function

edit

Mammalian mRNAs contain AU-rich elements (AREs) within their three prime untranslated regions. In yeast, 3-prime-to-5-prime mRNA degradation is mediated by the exosome, a multisubunit particle. EXOSC2 (which is homologous to the yeast Rrp4 protein) is a component of the human exosome.[7]
