CENPF(centromere protein F)是一种与细胞分裂密切相关的蛋白质,属于驱动蛋白家族(kinesin family)成员之一,也被称为有丝分裂驱动蛋白(mitotic kinesin)。它在细胞周期中发挥关键作用,特别是在有丝分裂(M期)期间,负责调控染色体的正确分离和纺锤体的形成。CENPF主要作用位点是染色体的着丝粒(centromere)和动粒(kinetochore),确保染色体在分裂过程中能够准确分配到子细胞中。此外,CENPF还参与细胞周期的G2/M期转换,帮助细胞进入有丝分裂阶段。CENPF的突变可能导致染色体不稳定、非整倍体(aneuploidy)或细胞分裂异常,进而引发多种疾病,尤其是癌症。研究发现,CENPF在多种恶性肿瘤(如乳腺癌、前列腺癌、肝癌等)中过表达,其高表达水平与肿瘤的侵袭性、转移能力和不良预后密切相关。CENPF过表达可能促进肿瘤细胞的异常增殖和基因组不稳定性,而降低其表达则可能抑制肿瘤生长并增强化疗敏感性。CENPF属于驱动蛋白家族,该家族成员通常具有ATP酶活性,能够利用ATP水解产生的能量沿微管运动,参与细胞内物质运输、细胞分裂和信号传导等过程。CENPF作为该家族的一员,具有典型的驱动蛋白结构域,但其功能更集中于有丝分裂调控。由于其在细胞分裂中的关键作用,CENPF已成为癌症治疗的潜在靶点,研究人员正在探索通过抑制CENPF表达或功能来开发新型抗癌药物。
This gene encodes a protein that associates with the centromere-kinetochore complex. The protein is a component of the nuclear matrix during the G2 phase of interphase. In late G2 the protein associates with the kinetochore and maintains this association through early anaphase. It localizes to the spindle midzone and the intracellular bridge in late anaphase and telophase, respectively, and is thought to be subsequently degraded. The localization of this protein suggests that it may play a role in chromosome segregation during mitotis. It is thought to form either a homodimer or heterodimer. Autoantibodies against this protein have been found in patients with cancer or graft versus host disease. [provided by RefSeq, Jul 2008]
