Gene Ontology Information

Protein Name	Rio1p
Description	Serine kinase involved in cell cycle regulation and rDNA integrity; associated with late pre-40S particles via its conserved C-terminal domain; prevents premature use of pre-40S particles in translation; association with pre-40S particles regulated by its catalytic ATPase site and likely occurs after the release of Rio2p from these particles; involved in cell cycle progression and processing of the 20S pre-rRNA into mature 18S rRNA; phosphorylates Rpa43p in anaphase to remove Pol I from rDNA
GO Terms: Biological Process	level 6: maturation of SSU-rRNA level 6: regulation of kinetochore assembly level 7: maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) level 7: regulation of exit from mitosis level 8: positive regulation of rRNA processing level 10: negative regulation of transcription by RNA polymerase II level 10: negative regulation of transcription by RNA polymerase I
