uniref

is a Data Source.

UniRef (Universal Protein Resource Reference Clusters) provides clustered sets of protein sequences from the UniProt Knowledgebase and selected UniParc records to obtain complete coverage. UniRef100 combines identical sequences and sub-fragments into a single UniRef entry, UniRef90 clusters sequences with 90% sequence identity, and UniRef50 clusters sequences with 50% sequence identity, providing speed and coverage tradeoffs for similarity searches.
