【摘要】:端粒重復(fù)序列結(jié)合因子2(telomeric-repeat binding factor 2,TRF2)是一種重要的端粒保護蛋白,與端粒保護蛋白1(protection of telomeres 1,POT1)、端粒重復(fù)序列結(jié)合因子1(telomeric-repeat binding factor 1,TRF1)、相互作用核蛋白2(TRF1-interacting nuclear protein 2,TIN2)、阻滯活化蛋白1(repressor activator protein 1,Rap1)以及TPP1,5個核心蛋白通過一系列相互作用共同形成端粒保護蛋白復(fù)合體(shelterin)以維持端粒結(jié)構(gòu)和功能的穩(wěn)定性和完整性。越來越多的研究顯示TRF2在多種腫瘤中異常表達并與腫瘤的發(fā)生,腫瘤細(xì)胞的耐藥以及腫瘤血管的生成密切相關(guān)。因此,本文就TFR2的結(jié)構(gòu)與生理功能,以及其在腫瘤發(fā)生,發(fā)展與治療中的作用研究進展進行綜述,以期為腫瘤的預(yù)防和治療提供新的思路。
[Abstract]:Telomere repeat binding factor 2 (telomeric-repeat binding factor 2) is an important telomere protection protein associated with telomere protection protein 1 (protection of telomeres 1 (POT1), telomere repeat sequence binding factor 1 (telomeric-repeat binding factor 1) and telomere repeat sequence binding factor 1 (TRF1). Interaction nucleoprotein 2 (TRF1-interacting nuclear protein 2), block activator protein 1 (repressor activator protein 1), Rap1) and five core proteins of TPP1, form telomere protection protein complex (shelterin) through a series of interactions to maintain the stability and integrity of telomere structure and function. More and more studies show that the abnormal expression of TRF2 in many kinds of tumors is closely related to the occurrence of tumor, drug resistance of tumor cells and angiogenesis of tumor. In this paper, the structure and physiological function of TFR2 and its role in tumorigenesis, development and treatment are reviewed in order to provide new ideas for the prevention and treatment of tumor.
