Function
Involved in pre-rRNA processing and ribosome assembly (PubMed:17108323, PubMed:17286797, PubMed:17369435, PubMed:21124873). Is associated with intranucleolar chromatin and pre-ribosomal particles and plays a role in controlling activation and repression of a specific subset of rRNA genes located in distinctive nucleolar organizer regions. Binds specifically rDNA chromatin and may be required to maintain rDNA chromatin structure, but is probably not required for the overall histone methylation status of 45S rRNA genes (PubMed:17108323, PubMed:17286797, PubMed:21124873). Involved in leaf polarity establishment by functioning cooperatively with AS1 to repress abaxial genes ARF3, ARF4, KAN1, KAN2, YAB1 and YAB5, and the knox homeobox genes KNAT1, KNAT2, KNAT6, and STM to promote adaxial development in leaf primordia at shoot apical meristems at high temperatures (PubMed:27334696).
