Blast similarity search
WebA BLAST search enables a researcher to compare a subject protein (called a query) with a database of sequences, and identify database sequences that resemble the query sequence above a certain threshold. Select the ‘Blast’ tab of the toolbar at the top of the page to run a sequence similarity search with the Blast program.

Local alignments algorithms (such as BLAST) are most often used. A global alignment should only be used on sequences that share significant similarity over most of their extents, and then it will sometimes return a better presentation. An example is the alignment of NP_004013 with NP_004014.
