Project Summary The goal of this proposal is to investigate the role of a novel Telomere associated protein that we termed TZAP in telomere homeostasis. Telomeres are essential nucleoprotein structures that cap chromosome ends. Alterations in telomere function are associated with various human diseases including cancer, premature aging, dyskeratosis congenita, aplastic anemia, and idiopathic pulmonary fibrosis. Our preliminary data show that TZAP is a novel telomere specific binding protein that is involved in telomere length homoeostasis. Several questions remain to be addressed to define the role of this novel telomere associated protein in telomere homeostasis. To address this questions, we have devised a research proposal that will define the mechanism of TZAP binding to telomeres, its role on telomere length regulation and the impact of its depletion in respect to genome stability and tissue homoeostasis.

项目摘要 这项提议的目标是研究一种新的端粒相关蛋白的作用，该蛋白可以 我们将TZAP称为端粒动态平衡。端粒是核蛋白的基本结构 那顶帽子染色体就结束了。端粒功能的改变与各种人类 疾病包括癌症、早衰、先天性角化不良、再生障碍性贫血和 特发性肺纤维化。我们的初步数据表明，TZAP是一种新的端粒特异性 参与端粒长度稳态的结合蛋白。还有几个问题有待解决 目的是确定这种新的端粒相关蛋白在端粒稳态中的作用。 为了解决这个问题，我们设计了一个研究方案，将定义这一机制 TZAP与端粒的结合、对端粒长度调节的作用及其影响 在基因组稳定性和组织同质性方面的耗竭。
