Examples
e.g. P00750, P05067-5, A4_HUMAN or acccgtggtcgctgctg... help
Enter a query protein or nucleotide sequence into the text area. Accepted input:
  • UniProtKB accession or identifier
  • bare sequence
  • sequence in FASTA format

BLAST programs available on ExPASy: help

  • blastp compares a protein query sequence against a protein sequence database.
  • blastn compares a nucleotide query sequence against a nucleotide sequence database.
  • tblastn compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames.
  • blastx compares a nucleotide query sequence translated in all reading frames against a protein sequence database.
blastp:protein query->protein sequence database
blastn:nucleotide query->nucleotide sequence database
tblastn:protein query->nucleotide sequence database
tblastx:nucleotide query->protein sequence database
