Ccdc81, also known as coiled-coil domain containing 81, has been implicated in multiple biological processes. Evidence suggests it may play a role in protein-protein interaction in centrosome organization and could potentially function as a cargo-binding protein in association with Dynein-VII [1]. It is also related to the HU/IHF superfamily, which has diverse functions in DNA-structuring and genome maintenance in different organisms [1].

In a proteomic analysis of mammalian sperm cells, Ccdc81 was identified as a centrosome-associated protein, indicating its possible importance in centrosome-related functions [3]. In a study on triploid Pacific oyster sterility, piRNAs potentially interact with the Ccdc81 gene, suggesting a role in spermatogenesis regulation [4]. In bioinformatics analysis for nasopharyngeal carcinoma, Ccdc81 was identified as one of the hub genes, which may be regarded as a diagnostic biomarker [5]. In a prognostic model for early-stage lung adenocarcinoma, Ccdc81 was among the methylation driver genes used to build a model for predicting patient survival risk [2].

In conclusion, Ccdc81 appears to be involved in centrosome-related functions, spermatogenesis in oysters, and may serve as a biomarker in diseases such as nasopharyngeal carcinoma and early-stage lung adenocarcinoma. These findings from various research models contribute to understanding its biological functions and its potential significance in disease diagnosis and prognosis.
