Similar proteinsi
Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:| 100% | UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry. |
| 90% | UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence). |
| 50% | UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster. |
