CCDC124 is a conserved eukaryotic ribosome-binding protein with dual roles in translational regulation and cell division. Its primary function involves ribosome hibernation: it binds translationally inactive 80S ribosomes and stabilizes their nonrotated conformation, facilitating ribosome preservation during nutrient deprivation 1. This interaction positions CCDC124 to bridge the decoding sites of the small ribosomal subunit with the GTPase activating center of the large subunit, enabling rapid translation reactivation through the Dom34-dependent recycling system 1. CCDC124 directly contacts ribosomal protein uL5, 25S rRNA, and tRNA-binding P/A-site regions 2. Beyond ribosomal functions, CCDC124 is required for proper late cytokinesis progression and localizes to the centrosome and cytokinetic midbody 32. Recent evidence identifies CCDC124 as a component of stress granules and a novel interaction partner of nucleophosmin-1 at the nucleolus 45. Structurally, CCDC124 is a highly disordered protein with aggregation propensity that forms dimeric/oligomeric states 2. Clinically, CCDC124 expression is upregulated in FOLFOX-responsive colorectal cancer patients and serves as an independent prognostic factor 6, and is part of a disulfidptosis-related gene signature predicting acute myeloid leukemia outcomes 7.
