文献和实验Generation and Application of Phospho-specific Antibodies for p53 and pRB
of phosphoproteins. We have improved methods for generation of phosphorylation site-specific antibodies and have successfully obtained antibodies for the analysis of most of the phosphorylation sites on p53 and RB proteins.
的激活和积累。Chk1和Chk2可以磷酸化p53的Ser20,促进p53的四聚化,增强其稳定性和活性。p53的Ser46磷酸化和其诱导细胞凋亡密切相关。p53的Ser392可以被CAK磷酸化,该位点磷酸化和p53的抑制生长功能及其DNA结合和转录激活有关。 简而言之,野生型P53可以帮助细胞抵御肿瘤发生,而磷酸化的P53则可能充当肿瘤发生的帮凶。 zhao22840718 p53 Signaling 顾benben
【求助】P53的翻译后修饰都有哪些? 怎样验证其修饰后与靶标启动子的结合活性的变化?
酰转移酶p300的结合增强,从而增加了p53的水平和稳定性。Ser15可在IR(电离辐射)或UV(紫外线)作用下发生磷酸化。同时IR 或UV 还可以分别通过活化CHK2(细胞周期关卡激酶2)和CHK1(细胞周期关卡激酶1)引起Ser20的磷酸化。 除常见的72位密码子多态性外,p53肿瘤还可显示一种少见的47位残基上的单核苷酸多态现象,野生型p53在此残基上编码脯氨酸,而在少数人群中编码的则是丝氨酸。此残基临近的Ser46被p38磷酸化后可以显著增强p53诱导凋亡的能力,而Ser-47多态
