Comparison of DNA sequences from different species is a fundamental method for identifying functional elements in genomes. Here, we describe the VISTA family of tools created to assist biologists in carrying out this task. Our first VISTA server at http://www-gsd.lbl.gov/vista/ was launched in the summer of 2000 and was designed to align long genomic sequences and visualize these alignments with associated functional annotations. Currently the VISTA site includes multiple comparative genomics tools and provides users with rich capabilities to browse pre-computed whole-genome alignments of large vertebrate genomes and other groups of organisms with VISTA Browser, to submit their own sequences of interest to several VISTA servers for various types of comparative analysis and to obtain detailed comparative analysis results for a set of cardiovascular genes. We illustrate capabilities of the VISTA site by the analysis of a 180 kb interval on human chromosome 5 that encodes for the kinesin family member 3A (KIF3A) protein.
比较不同物种的DNA序列是识别基因组中功能元件的基本方法。在此,我们描述了为协助生物学家完成这项任务而创建的VISTA工具家族。我们的第一个VISTA服务器(网址为http://www-gsd.lbl.gov/vista/ )于2000年夏季推出,旨在比对长基因组序列,并将这些比对结果与相关功能注释进行可视化展示。目前,VISTA网站包含多个比较基因组学工具,为用户提供了丰富的功能,可通过VISTA浏览器浏览大型脊椎动物基因组和其他生物群体预先计算好的全基因组比对结果,将自己感兴趣的序列提交到多个VISTA服务器进行各种类型的比较分析,并获取一组心血管基因的详细比较分析结果。我们通过分析人类5号染色体上一个180 kb的区间(该区间编码驱动蛋白家族成员3A(KIF3A)蛋白)来说明VISTA网站的功能。
