Cyclin O (CCNO) is a member of the cyclin protein family, first identified in 2010. that regulates cell cycle progression and is implicated in ciliogenesis. Unlike classical cyclins, CCNO lacks conserved cyclin box domains critical for cyclin-dependent kinase (CDK) binding, suggesting distinct regulatory mechanisms. The human CCNO gene is located on chromosome 5q11.2 and encodes a 150-amino acid protein. Functionally, CCNO localizes to centriolar satellites and basal bodies, playing a role in primary cilium formation by modulating microtubule dynamics through interactions with proteins like PCM1 and polycystin-2.
Mutations in CCNO are linked to severe ciliopathies, including primary microcephaly, retinal dystrophy, and congenital kidney disease. Notably, autosomal recessive CCNO mutations cause reduced generation of multiple motile cilia (RGMC), leading to respiratory distress and chronic infections due to impaired mucociliary clearance. CCNO-deficient cells exhibit delayed cell cycle re-entry from quiescence and defective DNA damage repair, highlighting its role in coordinating ciliogenesis with cell cycle checkpoints.
Recent studies emphasize its potential as a therapeutic target for cilia-related disorders, though its precise molecular partners and signaling pathways remain incompletely characterized. Research continues to explore its dual functions in cell cycle regulation and cilia biology, offering insights into developmental defects and tissue homeostasis.
