Exosome component 2Exosome component 2, also known as EXOSC2, is a protein which in humans is encoded by the EXOSC2 gene.FunctionMammalian mRNAs contain AU-rich elements within their three prime untranslated regions. In yeast, 3-prime-to-5-prime mRNA degradation is mediated by the exosome, a multisubunit particle. EXOSC2 is a component of the human exosome.InteractionsExosome component 2 has been shown to interact with: Exosome component 4, and Exosome component 7.
