InterProScan 5 (SOAP)


InterProScan 1) 2) 3) is a tool that combines different protein signature recognition methods into one resource. InterProScan 5 is a reimplementation of the traditional InterProScan 4.x series and adds features such as pathway annotations and signal peptide and transmembrane prediction using Phobius.

Nucleotide Sequences

To process nucleotide sequences using InterProScan 5:

  1. Translate your nucleotide sequence. The standalone version of InterProScan 4.x uses a basic ORF finding process to predict possible proteins for a nucleotide sequence. This uses EMBOSS sixpack to perform the translation and filter the resulting open reading frame (ORF) sequences by length. Alternative tools such as EMBOSS transeq are also available, but may require an additional filtering process to limit the ORF sequences to those above a certain length. These tools are available as part of the EMBOSS package, and via the Sequence Translation web services. For organisms where transcripts are spliced before translation, the use of more sophisticated gene prediction software is recommended to obtain probable protein sequences for the genes found.
  2. Filter ORFs by sequence length. Short sequences (<80 aa) are unlikely to have any signature matches, so unless there is additional evidence that the sequence occurs, short sequences can be discarded. The EMBOSS programs getorf and sixpack provide options to do length filtering when performing the translation.
  3. Significant hits from sequence similarity searches. The signatures used by InterProScan are based on known protein sequences so a filtering step by performing a BLAST or FASTA sequence similarity search with the ORF translations against the UniProtKB or UniParc protein sequence databases and only keeping sequences which have hits with E-values <0.001. In the case where an exact match is found to the sequence (using a sequence similarity search or services such as PICR or SeqCksum), you can go directly to the InterPro Matches databases to get the signature matches for the sequence (available in dbfetch and WSDbfetch as IPRMC or IPRMC UniParc, or on the InterPro FTP site).

Note: the standalone version of InterProScan 5 can perform the translation and ORF length filtering as part of the submission and is recommended if you need to perform large numbers of analysis and have access to the required resources. See for details.

The WSDL for the InterProScan SOAP service:



Get a list of the parameter names.

Arguments: none

Returns: a list of strings giving the names of the parameters.


Get details of a specific parameter.


  • parameterId: identifier/name of the parameter to fetch details of.

Returns: a wsParameterDetails describing the parameter and its values.

run(email, title, params)

Submit a job to the service.


Returns: a string containing the job identifier (jobId).


Get the status of a submitted job.


  • jobId: (required) job identifier.

Returns: a string containing the status.

The values for the status are:

  • RUNNING: the job is currently being processed.
  • FINISHED: job has finished, and the results can then be retrieved.
  • ERROR: an error occurred attempting to get the job status.
  • FAILURE: the job failed.
  • NOT_FOUND: the job cannot be found.

Further details can be found in Synchronous and Asynchronous Access: JDispatcher.


Get the available result types for a finished job.


  • jobId: (required) job identifier.

Returns: a list of wsResultType data structures describing the available result types.

getResult(jobId, type, parameters)

Get the result of a job of the specified type.


  • jobId: (required) job identifier.
  • type: (required) string specifying the result type to fetch. See getResultTypes(jobId) for details of the available types.
  • parameters: optional list of wsRawOutputParameter used to provide additional parameters for derived result types.

Returns: the result data for the specified type, base64 encoded. Depending on the SOAP library and programming language used the result may be returned in decoded form. For some result types (e.g. images) this will be binary data rather than a text string.
