Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding activity and mRNA 3'-UTR AU-rich region binding activity. Predicted to be involved in RNA metabolic process; positive regulation of cell growth; and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within rRNA processing. Predicted to be located in cytoplasm and nuclear lumen. Predicted to be part of cytoplasmic exosome (RNase complex) and nuclear exosome (RNase complex). Is expressed in early conceptus. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia. Orthologous to human EXOSC9 (exosome component 9). [provided by Alliance of Genome Resources, Apr 2022]
