ARF为一抑癌蛋白主要通过p53途径使细胞停滞于G 1期和G 2/M 期,导致细胞衰老或凋亡,对肿瘤的发生发展起重要的抑制作用。ARF基因和蛋白质结构由于IN K4a基因能够编码两种蛋白,故称为IN K4a/ARF位点,该位点有4个外显子,其中外显子11ol ,2和3编码p16州K48蛋白,长度为156氨基酸残基。而外显子113,位于外显子...

By functioning specifically to oppose abnormally prolonged and sustained proliferative signals produced by activated oncogenes, the ARF tumour suppressor antagonizes functions of MDM2 to induce protective responses that depend on the p53 transcription factor and its many target genes. However, ARF has ...

ARF has now been reported to physically interact with more than 25 other proteins, at least some of which have been postulated to be responsible for its p53-independent functions. These include proteins involved in ribosome biogenesis, transcriptional regulation, the DNA-damage response, apoptosis and...

ARF对p53基因网络的调控作用
《Caspases切割ARF-BP1调控p53信号通路的机制》是依托厦门大学,由张四清担任项目负责人的面上项目。项目摘要 ARF-BP1是抑癌基因p53的主要负调控者之一,通过泛素化修饰降解p53. 但对ARF-BP1的调控以及这些调控如何影响p53的功能却知之甚少,亟待深入研究。本申请项目发现ARF-BP1是一个新的重要caspase底物。caspase切割...
