UniProtKB - Q9CQS5 (RIOK2_MOUSE)
Protein
Serine/threonine-protein kinase RIO2
Gene
Riok2
Organism
Mus musculus (Mouse)
Status
Functioni
Serine/threonine-protein kinase involved in the final steps of cytoplasmic maturation of the 40S ribosomal subunit. Involved in export of the 40S pre-ribosome particles (pre-40S) from the nucleus to the cytoplasm. Its kinase activity is required for the release of NOB1, PNO1 and LTV1 from the late pre-40S and the processing of 18S-E pre-rRNA to the mature 18S rRNA. May regulate the timing of the metaphase-anaphase transition during mitotic progression, and its phosphorylation, may regulate this function.By similarity
