Importance of the amino acids at positions 299-308 of the tumor suppressor p53 molecule for nucleotide excision repair from the aspect of p53:XPB interaction
碩士 === 國立清華大學 === 分子醫學研究所 === 97 === 抑癌因子p53蛋白可以促進細胞修復UVC紫外線所造成的DNA損傷,並且增加照射輻射後的細胞存活率。核苷酸切除修復路徑(NER)是哺乳動物細胞去除UVC紫外線造成的DNA損傷的唯一途徑。p53可能藉由轉錄活化(transaction-dependent)或是非轉錄活化(transaction-independent)達成促進NER的功能。我們之前利用彗星分析法的研究指出p53於核萃取物(NE)去除紫外線導致的DNA損傷中扮演必要的角色。在此論文研究中,我們進一步確定p53蛋白是利用第299到308序列(LPPGSTKRAL...
