rDNA-derived lncRNAs are involved in the regulation of nucleolar functions. Schematics of the molecular mechanisms under the functions of pRNA (A), PAPAS (B), rIGSRNAs (C), asincRNAs (D), and PNCTR (E). Regions where the rDNA-derived lncRNAs are transcribed from are marked along the human rDNA repeat. + 1 indicates the transcription start site (TSS) of rRNA gene
