Batch retrieval & ID mapping

You can use the ‘ID Mapping’ feature in UniProt to download UniProt entries corresponding to a list of UniProt accessions. You can also use this feature to convert database identifiers from UniProt to external databases or vice versa. 

Batch retrieval of UniProtKB entries

Try it for yourself….

1. Click on ‘ID Mapping’ in the header bar.

2. Provide your list of UniProtKB identifiers in the box. You can separate the identifiers by a whitespace (space, tab, new line) or by a comma. You may also upload an input file from your machine using the link given.

3. For the default batch download of UniProtKB entries, leave the ‘From’ and ‘To’ dropdowns on their default selection of ‘UniProtKB’ and click on the ‘Go’ button.

You get a results page where you can further filter the results, edit the table columns to add or remove information and download the information in various formats. The results of this job will stay on the Tools dashboard for 7 days.

Converting UniProt identifiers to external identifiers (or vice versa)

Try if for yourself…

Let’s assume that we have a list of RefSeq identifiers that we would like to convert to UniProtKB identifiers.

1. Click on ‘Retrieve/ID Mapping’ in the header bar.

2. Provide your list of RefSeq identifiers in the box. You can separate the identifiers by a whitespace (space, tab, new line) or by a comma. You can also upload an input file from your machine using the link provided (Figure 45 – interactive image).

3. Select the ‘From’ database as ‘RefSeq Protein’ and the ‘To’ database as ‘UniProtKB’ (default selection). As you will see from the ‘From’ and ‘To’ dropdowns, you can convert various types of identifiers to UniProtKB and vice versa.

You will get a results page with your converted identifiers ready for download.
