Predicted to enable protein heterodimerization activity; protein-macromolecule adaptor activity; and scaffold protein binding activity. Predicted to be involved in mesenchymal cell differentiation; nucleolar large rRNA transcription by RNA polymerase I; and regulation of translation. Predicted to be located in cytosol; fibrillar center; and nucleoplasm. Predicted to be active in nucleolus. Human ortholog(s) of this gene implicated in Treacher Collins syndrome and Treacher Collins syndrome 1. Orthologous to human TCOF1 (treacle ribosome biogenesis factor 1).
