我们在打开数据库之后,在菜单栏可以看到很多种来进行相互作用关系预测的选项。如果我们有一个目标蛋白,想要查看这个蛋白的可能的相互作用蛋白可以选择Protein by name;如果我们有很多蛋白,想要查看这些蛋白之间的相互作用关系,那就可以选择Multiple proteins。 由于我们在之前的差异表达分析的时候,可以得到很多基因,所以我们...
上述的网络我们就称之为蛋白质相互作用网络,protein-protein interaction network, 即PPI网络。要看懂上面这张图,需要理解以下两个方面 1. 节点(node) 图中每个节点表示一个蛋白,由于真核生物的可变剪切和转录后修饰,1个蛋白编码基因可能会产生多个蛋白,这里将由同一个基因产生的不同isoform进行了合并,在节点上标记...
PROTEIN-protein interactionsPYTHON programming languageFunctional enrichment analysis is an analytical method to extract biological insights from gene expression data, popularized by the ever-growing application of high-throughput techniques. Typically, expression profiles are generated for hundreds to thousands ...
In the STRING database, for example, each stored protein-protein interaction has a score (between zero and one) representing its confidence. The supporting evidence for each interaction is divided into seven “evidence channels.” The experiments channel is formed by results from the lab that prov...
The STRINGdb package provides a R interface to the STRING protein-protein interactions database (http://www.string-db.org),从这个介绍可看出,StringDB包就是连接String网站的数据库进行蛋白互作网络分析的,这个R包半年更新一次,基本上也跟String数据库的更新速度差不多,所以数据的实时性还是有保证的,下面...
