Using MouseBLAST - Searching by Sequence ID
More Help

This help document answers the following questions:

Can I search a sequence if I know the sequence accession ID?

Yes. You can search a sequence by entering the sequence accession identifier, (also known as the sequence accession ID, sequence ID, seq ID, or accession ID). To have MouseBLAST fetch your sequence, find Option 1 in the Query sequence section of the MouseBlast query form and do the following:

  1. In the box beside Sequence ID, enter the unique identifier for the sequence (e.g., NM_021099).
  2. Select the remote public sequence database where your unique identifier is valid. (For NM_021099, the correct database is RefSeq.)
  3. Click Search.
  4. The MouseBLAST Query Results report displays any sequence matches. Click to place a check mark beside any you wish to download or forward to MouseBLAST.

Are there examples of sequence ID/sequence database combinations?

The following table shows examples of sequence database and sequence ID combinations. Note: Items in the Unique Seq ID column are representative of IDs in databases listed in the Sequence Provider column; however, on any given day querying by that ID may not yield a result, due to database updates or changes.

What if the MouseBLAST sequence retrieval tool is unavailable?

If the sequence retrieval tool is not working, MouseBLAST returns an error message to that effect. Try to obtain your sequence from a web resource such Entrez at the NCBI or ExPASy at the Swiss Institute of Bioinformatics (SIB).

What if the sequence identifier is invalid?

MouseBLAST returns an error message when a unique sequence identifier is not valid. Either retype the identifier and repeat the search or enter a different identifier.
