使用Interpro数据库，可以将蛋白质序列进行家族分类，预测其结构域和重要位点。Interpro综合了多种不同的数据库来构成一个综合的Interpro数据库。这些数据库有:PROSITE.HAMAP,Pfam,PRINTS,ProPom,SMART/TIGRFAMs,PIRSF,SUPERFAMILY,CATH-Gene3D,PANTHER

方法1网页版

http://www.ebi.ac.uk/interpro/

将序列粘贴到输入框中进行Interpro注释。

优点：方便。。。

缺点：输入必须为蛋白质序列;InterProScan每次查询一次性最多能比对25条蛋白质序列。

方法2使用EBI提供的脚本程序进行远程比对  

EBI：The European Bioinformatics Institute

推荐使用EBI提供的perl程序来进行Interpro注释。程序能将序列发送到官方服务器进行InterPro注释，再将结果返回本地。

在这里，有perl,Python和Ruby程序各一支。分别是：iprscan_lwp.pl,iprscan_urllib2.py和iprscan_net_http.rb

[Required]

  seqFile            : file : query sequence ("-" for STDIN, @filename for
                              identifier list file)

[Optional]

      --appl         : str  : Comma separated list of signature methods to run,
                              see --paramDetail appl.
      --goterms      :      : retrieve GO terms
      --nogoterms    :      : do not retrieve GO terms
      --pathways     :      : retrieve pathway terms
      --nopathways   :      : do not retrieve pathway terms
      --multifasta   :      : treat input as a set of fasta formatted sequences
 
[General]

  -h, --help         :      : prints this help text
      --async        :      : forces to make an asynchronous query
      --email        : str  : e-mail address
      --title        : str  : title for job
      --status       :      : get job status
      --resultTypes  :      : get available result types for job
      --polljob      :      : poll for the status of a job
      --jobid        : str  : jobid that was returned when an asynchronous job
                              was submitted.
      --outfile      : str  : file name for results (default is jobid;
                              "-" for STDOUT)
      --useSeqId     :      : use sequence identifiers for output filenames.
                              Only available in multifasta or list file modes.
      --maxJobs      : int  : maximum number of concurrent jobs. Only
                              available in multifasta or list file modes.
      --outformat    : str  : result format to retrieve
      --params       :      : list input parameters
      --paramDetail  : str  : display details for input parameter
      --quiet        :      : decrease output
      --verbose      :      : increase output

Synchronous job:

  The results/errors are returned as soon as the job is finished.
  Usage: iprscan5_lwp.pl --email <your@email> [options...] seqFile
  Returns: results as an attachment

优点：

缺点：不能进行核苷酸序列的注释
