NOTICE: The MGI MouseBLAST resource will be discontinued during October, 2015. At that point, BLAST requests in MGI will be forwarded to the BLAST resource at NCBI instead.
For more information on this upcoming change, see: BLAST help.
Use MouseBLAST to search a sequence within mouse/rodent sequence databases to find matching sequences that may be associated with mouse genes. Query results may be linked to MGI mouse gene records. Searches are performed using WU-BLAST 2.0. All sequence databases are updated on a weekly basis.

Masking options
For DNA queries
For protein queries:SEG - mask low-complexity regions.
XNU - mask short tandem repeats.
Query sequence
You may enter your query sequence (maximum of 50,000 letters) using one of four options.
Option 1: Query by sequence accession ID.
    Sequence ID:(e.g., M15131)
    Sequence database:

Option 2: Query by genomic sequence interval (GRCm38).
    Coordinates  Between:  
Option 3: Enter a sequence. Most web browsers have a limit of 20,000 letters when pasting a sequence into this form.
    Sequence(FASTA,GCG, or free-text format):
Option 4: Upload a sequence file.
    Upload sequence file(FASTA,GCG, or free-textformat):
Output options
Number of scores to show: Number of alignments to show:
Exclude alignment of query sequence to itself if found in the database searched.
