Background Information

EXOSC8 (exosome component 8), also known as p9 or CIP3, is a component of the exosome multi-enzyme ribonuclease complex, that degrades or processes messenger RNA. It belongs to the RNase PH family and localizes to the nucleolus. EXOSC8 is one of the six RNase-PH domain subunits of the exosome. EXOSC8 is part of the central hexamer channel of the exosome. EXOSC8 mutations could alter mRNA metabolism and cause hypomyelination with spinal muscular atrophy and cerebellar hypoplasia.
