About   Help   FAQ
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):
