| 1 | 丝氨酸/苏氨酸蛋白磷酸酶与DNA损伤应答显示文摘DNA损伤应答(DNA damage response,DDR)是维持基因组稳定性的核心机制,对DDR的研究不仅有助于阐明癌症发生发展的机理,同时也为癌症治疗和抗癌新药开发提供生物学基础。蛋白质翻译后修饰,尤其是蛋白激酶介导的磷酸化修饰和蛋白磷酸酶介导的去磷酸化修饰,参与调控绝大多数的生命活动过程,包括DDR。对蛋白激酶ATM/ATR/CHK2/CHK1介导的DDR的研究已经比较透彻,但是对蛋白磷酸酶在DDR中的功能研究还有待加强和深入。比较全面地综述丝氨酸/苏氨酸蛋白磷酸酶在DDR中的功能并探讨在抗癌新药开发中的前景。 | 彭斌 王静 胡源 许兴智 | 2014 | 生命科学2014，26，11： | 4 |
| 2 | Serine/threonine protein phosphatases in DNA damage response显示文摘DNA damage response (DDR) is among the most important of the mechanisms that maintain genome stability which, when destabilized, predisposes organs to cancer. Reversible phosphorylation mediated by protein kinases and protein phosphatases regulates most, if not all, cellular activities, including DDR. Protein kinase inhibitors have become the main focus of targeted therapy and anticancer drug development. However, our limited knowledge of protein phosphatase function is compromising our capacity to develop therapeutic agents against phosphatases. In this review, we summarize the roles of serine/threonine protein phosphatases involved in DDR and propose that in situ dephosphorylation of phosphoproteins by protein phosphatases, instead of proteasome-mediated degradation of phosphoproteins, is mainly employed by cells. | LIU Bo XU XingZhi | 2011 | Chinese Science Bulletin2011，56，30： | 3 |
