Many newly detected point mutations are located in protein-coding regions of the human genome. Knowledge of their effects on the protein's 3D structure provides insight into the protein's mechanism, can aid the design of further experiments, and eventually can lead to the development of new medicines and diagnostic tools.
In this article we describe HOPE, a fully automatic program that analyzes the structural and functional effects of point mutations. HOPE collects information from a wide range of information sources including calculations on the 3D coordinates of the protein by using WHAT IF Web services, sequence annotations from the UniProt database, and predictions by DAS services. Homology models are built with YASARA. Data is stored in a database and used in a decision scheme to identify the effects of a mutation on the protein's 3D structure and function. HOPE builds a report with text, figures, and animations that is easy to use and understandable for (bio)medical researchers.
We tested HOPE by comparing its output to the results of manually performed projects. In all straightforward cases HOPE performed similar to a trained bioinformatician. The use of 3D structures helps optimize the results in terms of reliability and details. HOPE's results are easy to understand and are presented in a way that is attractive for researchers without an extensive bioinformatics background.
许多新发现的点突变位于人类基因组的蛋白质编码区。了解它们对点突变蛋白质 3D 结构的影响,可以深入了解蛋白质的作用机制,有助于进一步实验的设计,最终可能会开发出新的药物和诊断工具。
本文描述了 HOPE,这是一个全自动的程序,可以分析点突变的结构和功能影响。HOPE 从广泛的信息来源收集信息,包括使用 WHAT IF Web 服务计算蛋白质的 3D 坐标、来自 UniProt 数据库的序列注释以及 DAS 服务的预测。同源模型由 YASARA 构建。数据存储在数据库中,并在决策方案中使用,以确定突变对蛋白质 3D 结构和功能的影响。HOPE 构建了一个带有文本、图形和动画的报告,易于(医)生物研究人员使用和理解。
我们通过将 HOPE 的输出与手动进行的项目的结果进行比较来测试 HOPE。在所有简单的情况下,HOPE 的表现与受过训练的生物信息学家相似。使用 3D 结构有助于提高结果的可靠性和详细程度。HOPE 的结果易于理解,并以吸引没有广泛生物信息学背景的研究人员的方式呈现。
