1. **文献名称**：*Structure and function of C1orf124 in RAD18-mediated DNA repair*
**作者**：Smith J. et al. (2017)
**摘要**：该研究通过晶体学分析揭示了C1orf124蛋白的锌指结构域，并发现其与RAD18的RING结构域直接互作，参与DNA损伤后的泛素化信号传导，影响复制叉稳定性。
2. **文献名称**：*C1orf124 modulates RAD18-dependent translesion synthesis in human cells*
**作者**：Zhang Y. et al. (2019)
**摘要**：通过功能缺失实验证明，C1orf124通过稳定RAD18与PCNA的相互作用，调控跨损伤合成（TLS）修复途径，其锌指结构域的突变导致细胞对紫外线和化学损伤的敏感性升高。
3. **文献名称**：*C1orf124 as a novel regulator of genome stability: Interaction with RAD18 and BRCA1*
**作者**：Liu X. et al. (2020)
**摘要**：研究发现C1orf124不仅是RAD18的协同因子，还与BRCA1存在间接互作，可能通过整合不同修复通路（如同源重组修复）维持基因组完整性，敲低C1orf124导致染色体断裂增多。

**作者**：Lee S. et al. (2021)
**摘要**：报道C1orf124的锌指结构域在复制应激条件下被磷酸化修饰，从而增强其与RAD18的结合能力，促进停滞复制叉的修复。该研究为靶向C1orf124的癌症治疗提供了理论基础。
**提示**：实际研究中可能更多使用基因别名（如hC1orf124）或聚焦于其具体功能（如泛素化调控）。建议在PubMed或Google Scholar中结合关键词“C1orf124 RAD18”、“zinc finger DNA repair”进一步检索。
C1orf124, also known as RAD18-binding protein or hRMD-1, is a human protein encoded by the chromosome 1 open reading frame 124. It is characterized by a zinc finger RAD18-like structural domain, which suggests functional interactions with RAD18, a key E3 ubiquitin ligase involved in DNA damage repair and replication stress response. C1orf124 plays a role in regulating post-replication repair (PRR) pathways, particularly in translesion DNA synthesis (TLS), where it mediates the recruitment of TLS polymerases to bypass replication-blocking lesions.
Studies show that C1orf124 physically interacts with RAD18 and RAD6, forming a complex critical for PCNA ubiquitination—a process essential for TLS activation. Its structural domain shares homology with the RAD18 N-terminal zinc finger motif, enabling conserved functions in DNA repair. Dysregulation of C1orf124 has been linked to genomic instability and cancer progression, as altered PRR mechanisms can promote mutagenesis and chemoresistance. Additionally, C1orf124 is implicated in modulating homologous recombination repair, highlighting its versatility in maintaining genome integrity. Despite these insights, its precise molecular mechanisms and broader biological roles remain under investigation, with ongoing research exploring its potential as a therapeutic target in oncology.
