项目摘要

DESCRIPTION (provided by applicant): Protein switches hold great promise as selective protein therapeutics and as biosensors for diagnostic and basic science applications; however, the creation of such proteins has proven difficult. We propose to create protein switches for these applications using a combinatorial method we developed that views all existing proteins as potential input and output modules for the desired switch. We will create a protein switch that will activate a prodrug only in cancer cells. Such a switch would have potential as a targeted therapeutic for the treatment of cancer. In addition, we will create switches to be used as sensors for kinases in vitro and in live cells. Switches to be used as sensors will be developed on a platform such that sensors for other proteins will be more readily created. Experiments proposed will also inform the study of how best to create switches. PUBLIC HEALTH RELEVANCE: Engineered protein switches hold great promise as selective protein therapeutics and as biosensors for diagnostic and basic science applications. We will develop switches designed for the treatment of cancer and switches designed to be used as sensors for the detection and quantification of important protein kinases in vitro and in live cells.

描述（由申请人提供）：蛋白质开关作为选择性蛋白质疗法和作为诊断和基础科学应用的生物传感器具有巨大的希望；但是，事实证明，这种蛋白质的创建很困难。我们建议使用组合方法为这些应用创建蛋白质开关，我们开发了所有现有蛋白质是所需开关的潜在输入和输出模块。我们将创建一个仅在癌细胞中激活前药的蛋白质开关。这样的转换将具有针对癌症治疗的靶向治疗方法。此外，我们将创建开关，以用作体外和活细胞中激酶的传感器。将用作传感器的开关将在平台上开发，以便更容易创建其他蛋白质的传感器。提出的实验还将告知研究如何最好地创建开关。公共卫生相关性：工程蛋白质开关作为选择性蛋白质疗法和作为诊断和基础科学应用的生物传感器具有巨大的希望。我们将开发用于治疗癌症的开关，并将其用作传感器用于检测和定量重要蛋白激酶在体外和活细胞中的传感器。
