Search for Sequences in UniProt searches the UniProt Knowledgebase (UniProtKB). UniProtKB contains UniProtKB/Swiss-Prot entries, which are manually curated, and UniProtKB/TrEMBL entries, which are annotated by automated systems.
To open the tool, go to:
Download | Search for Sequences in UniProt ()
One or more search terms can be entered, and a table of entries matching the search terms is returned. Rows in that table can be selected and the corresponding UniProtKB entries downloaded and opened, or downloaded and saved (figure 10.4).
Searching is described in more detail in UniProt search options.
Working with results returned by a search is described in Handling of UniProt search results.
