Description_x000D_ General description_x000D_ This gene encodes a core component of the exosome. The mammalian exosome is required for rapid degradation of AU rich element-containing RNAs but not for poly(A) shortening. The association of this protein with the exosome is mediated by protein-protein interactions with ribosomal RNA-processing protein 42 and ribosomal RNA-processing protein 46.

It is also essential for epigenetic gene regulation. It endogenously suppresses erythroid maturation. Within the complex, Exosc1 (exosome component 1) associates with Exosc6 to stabilize the complex. The binding of Exosc10 to Exosc1, Exosc6, and Exosc8 enhances the activity of the complex and positions Exosc1 for RNA binding.
