Peptide Search Module
Search for specific peptides across all genes and protein isoforms.
The Peptide Search module uses BLASTP to search a peptide sequence across all genes and protein isoforms in the IsoPepTracker database, identifying homologous matches with detailed alignment statistics.
Search Parameters
Peptide Sequence – enter the query peptide sequence
e-value Threshold – set the maximum e-value for filtering hits
Min Identity % – minimum sequence identity percentage
Max Targets – maximum number of target hits to return
How to Use
Enter your peptide sequence.
Configure BLASTP search parameters (e-value, minimum identity, max targets).
Run the search and view results ranked by identity and bit score.
Select a hit to view the gene structure visualization with the BLAST match mapped onto protein isoforms.
