Enables several functions, including TFIIB-class transcription factor binding activity; snoRNA binding activity; and snoRNP binding activity. Involved in several processes, including box H/ACA RNA metabolic process; positive regulation of transcription, DNA-templated; and regulation of protein import into nucleus. Located in nucleolus and nucleoplasm. Part of box C/D RNP complex and box H/ACA snoRNP complex. Orthologous to human NOLC1 (nucleolar and coiled-body phosphoprotein 1).
