Enables RNA polymerase I core binding activity and rDNA binding activity. Involved in several processes, including determination of adult lifespan; insulin receptor signaling pathway; and nucleolar large rRNA transcription by RNA polymerase I. Located in nucleolus and nucleoplasm. Is expressed in several structures, including germ line; germline precursor cell; gonadal sheath cell; nervous system; and somatic cell. Orthologous to human NOLC1 (nucleolar and coiled-body phosphoprotein 1).
WB Description
dao-5 encodes a predicted nucleolar phosphoprotein related to Saccharomyces cerevisiae SRP40 and the vertebrate Nopp140 proteins that may play a role in rRNA gene transcription and nucleolar structural organization; dao-5 expression is negatively regulated by the DAF-2/insulin-like receptor and positively regulated by the DAF-16/fork-head transcription factor, suggesting that dao-5 may be involved in life-span determination; dao-5 is strongly expressed in dauer larvae; DAO-5 localizes to nucleoli.
