    Summary
    Predicted to enable mRNA 3'-UTR AU-rich region binding activity. Involved in RNA metabolic process. Located in nucleolus. Part of cytoplasmic exosome (RNase complex) and nuclear exosome (RNase complex). Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 1D. Orthologous to human EXOSC9 (exosome component 9). [provided by Alliance of Genome Resources, Dec 2024]
