The p53 protein family consists of three transcription factors: p53, p63, and p73. These proteins share significant structural and functional similarities and each has unique biological functions as well. Although the role of p53 in cellular stress is extensively studied, many questions remain about p63 and p73. In this review we summarize current data on functional interactions within the p53 family, their regulation and roles in response to genotoxic stress. We also discuss the significance of p73 and p63 for cancer therapy and outline novel approaches in development of therapeutic drugs that specifically target the p53 family.
p53蛋白家族由三种转录因子组成:p53、p63和p73。这些蛋白具有显著的结构和功能相似性,且各自也具有独特的生物学功能。尽管p53在细胞应激中的作用已得到广泛研究,但关于p63和p73仍存在许多问题。在本综述中,我们总结了p53家族内功能相互作用的当前数据,它们在响应基因毒性应激时的调节及作用。我们还讨论了p73和p63在癌症治疗中的意义,并概述了开发特异性靶向p53家族的治疗药物的新方法。
