姐妹染色单体凝聚发生于DNA复制时期，由黏合素调节，并且依赖于细胞分裂周期相关蛋白5(CDCA5)及黏合素的乙酰化。WAPL可以促进黏合素与DNA解离，CDCA5可以拮抗WAPL的作用，通过稳定黏合素与DNA的结合从而稳定姐妹染色单体凝聚。CDCA5 mRNA在多种肿瘤细胞株中具有较高的转录水平，提示CDCA5可能与肿瘤细胞较高的恶性增殖活性有关，并且已经在肝癌、肺癌等多种肿瘤中得到证实，CDCA5可能是肿瘤治疗的潜在靶向分子。“,”Cohesion between sister chromatids occurs during DNA replication, is regulated by cohesin, and depends on acetylation of cell division cycle associated 5 (CDCA5) and cohesin. WAPL can promote dissociation of cohesin from DNA, and CDCA5 can antagonize the effect of WAPL and stabilize sister chromatids cohesion by stabilizing the binding of cohesin to DNA. CDCA5 mRNA has a high transcription level in a variety of tumor cell lines, suggesting that CDCA5 may be related to the higher malignant proliferation activity of tumor cells, and has been confirmed in various tumors such as liver cancer and lung cancer, and CDCA5 may be a potential targeted molecule for the treatment of malignant tumors.
