Tcof1 - treacle ribosome biogenesis factor 1

Predicted to enable protein heterodimerization activity; protein-macromolecule adaptor activity; and scaffold protein binding activity. Acts upstream of or within nucleolar large rRNA transcription by RNA polymerase I. Predicted to be located in cytosol; fibrillar center; and nucleoplasm. Predicted to be active in nucleolus. Is expressed in several structures, including appendicular skeleton; branchial arch; facial prominence; genitourinary system; and neural ectoderm. Used to study Treacher Collins syndrome. 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).
