Has a role in chromosome maintenance and is involved in mitotic exit. Inhibits the action of CDC14 by sequestering it in the nucleolus. Also binds to RNA polymerase I and stimulates rRNA synthesis. Influences RDNA chromatin by tethering SIR2 to rDNA in the nucleolus. Component of the RENT complex which is composed of at least NET1, CDC14 and SIR2 (PubMed:12056824, PubMed:11511359). Interacts with NSI1 (PubMed:22362748). Phosphorylated by CDC5. Present with 1590 molecules/cell in log phase SD medium. To yeast YKR010c.
