Predicted to enable mRNA 3'-UTR AU-rich region binding activity. Predicted to be involved in RNA metabolic process. Predicted to act upstream of or within rRNA processing. Predicted to be located in cytoplasm and nucleus. Predicted to be 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).
