BLAST basic local alignment search tool is a tool for comparing primary biological sequence information such as the amino-acid sequences of proteins. A 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. Figure 38 Figure 38 The Blast input page interactive image. Jobs have unique identifiers, which depending on the job type can be used in queries e. Job identifiers and the related data are kept for seven days, and are then deleted. Advanced users may wish to change the default parameters to optimise their search.

The main page shows the sequences aligned and a left hand panel provides highlight options. Queries can be submitted to the Align tool directly through the UniProt basket feature, uniprot blast.

Federal government websites often end in. The site is secure. Enter coordinates for a subrange of the query sequence. Sequence coordinates are from 1 to the sequence length. The range includes the residue at the To coordinate. Use the browse button to upload a file from your local disk.

Uniprot blast

The program compares nucleotide or protein sequences and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families. Enter the query sequence in the search box, provide a job title, choose a database to query, and click BLAST :. Under the Alignments tab next to Alignment view select Pairwise with dots for identities. View the Descriptions tab to see a list of significant alignments. Note that the first match is a synthetic construct that is, the sequence was computationally derived and is not associated with any organism :.

Figure 9. Figure 6. The job identifier can be used to access your sequence alignment at any time for up to seven days from when you first ran the query. The detailed alignment table shows the alignment graphically with the query shown in black and the subject hit color coded to reflect identity following the same scale as the overview table. You will get a results page with a table showing the mapping between your input IDs and their corresponding IDs from your selected database as shown in Figure Queries can be submitted to the Align tool directly through UniProt search result pages. You can select entries in your alignment table by clicking on the checkboxes to their left and then submit them to the Blast tool, the align tool or add them to your basket. Jobs have unique identifiers, which depending on the job type can be used in queries e. My playlists. You may need to increase the E threshold if you have a very short query sequence, to detect very weak similarities, or similarities in a short region, or if your sequence has a low complexity region and you use the "filter" option Matrix The matrix assigns a score for each position in an alignment. Enter either a protein or nucleotide sequence or a UniProt identifier into the form field Figure 38 — interactive image. The UniProt Align results appear as shown in Figure Select your target database.

A 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.

One of these is the option to change the target database for running your search against, which is UniProtKB by default. When you are ready to analyze the entries in your basket, click on the basket to open it. Figure Hits Limits the number of returned alignments. Restrict the species. If you have a list of UniProt IDs and would like to retrieve results for all of these, paste your list into the input box provided or upload a file. You may need to increase the E threshold if you have a very short query sequence, to detect very weak similarities, or similarities in a short region, or if your sequence has a low complexity region and you use the "filter" option.
