Navigating the UniProt tools

UniProt provides four main analysis tools:

• the Basic Local Alignment Search Tool (BLAST) for sequence search
• the ‘Align’ multiple sequence alignment tool
• the ‘Retrieve/ID Mapping’ tool where you can submit a list of identifiers to retrieve the corresponding UniProt entries, or map UniProt identifiers to an external database
• the ‘Peptide search’ tool which allows you to submit short peptide sequences of at least 3 residues and find all UniProtKB sequences which have an exact match to the query sequence

You can navigate to these tools by clicking on their corresponding links in the header or the appropriate tile (Figure 12).
