Coiled-coil domain-containing protein 9 (CCDC9) is a conserved eukaryotic protein characterized by its namesake coiled-coil structural motifs, which mediate protein-protein interactions and macromolecular assembly. It belongs to the CCDC family, members of which are broadly implicated in cytoskeletal organization, intracellular trafficking, and signal transduction. CCDC9 is ubiquitously expressed, with higher levels observed in tissues like the brain, kidneys, and lungs. Structurally, it contains multiple α-helical regions that form coiled-coil domains, enabling dimerization or oligomerization with binding partners such as PARD6B, a regulator of cell polarity.
Functionally, CCDC9 participates in microtubule dynamics, ciliogenesis, and cell cycle regulation. Studies link it to autophagy modulation via interactions with the ULK1 complex and Golgi apparatus integrity maintenance. Its dysregulation has been associated with diseases, including cancer and ciliopathies. For example, CCDC9 overexpression correlates with tumor progression in breast and hepatocellular carcinomas, while its deletion or mutations have been identified in neurological disorders and retinal degeneration linked to ciliary dysfunction.
Despite progress, the precise molecular mechanisms of CCDC9 remain incompletely characterized. Ongoing research focuses on its role in cellular stress responses, ciliary signaling pathways, and potential as a therapeutic target. Its dual involvement in both proliferative and structural cellular processes highlights its biological versatility and disease relevance.
