    Summary
    Enables chromatin binding activity and protein kinase activity. Involved in maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA); regulation of RNA metabolic process; and regulation of exit from mitosis. Acts upstream of or within negative regulation of transcription by RNA polymerase II and regulation of kinetochore assembly. Located in several cellular components, including fungal-type vacuole; mitochondrion; and nucleolar chromatin. Is active in kinetochore. Used to study colon cancer. Orthologous to human RIOK1 (RIO kinase 1). [provided by Alliance of Genome Resources, Oct 2024]
