About ECOD

ECOD (Evolutionary Classification of Protein Domains) is a hierarchical classification of protein domains based on evolutionary relationships. It combines automated sequence and structure analysis with manual curation.

Search Tips

123456789Search by UID (6-9 digit number)
e1abcA1Search by ECOD domain ID
P12345Search by UniProt accession
1abcSearch by PDB ID (shows all domains from that structure)
1.2.3Search by cluster ID (shows domains in that classification)
PF00077Search by Pfam accession (shows all ECOD families mapped to that Pfam)
CL0129Search by Pfam clan (shows all ECOD families across the clan)
kinaseSearch by keyword (searches cluster names and protein annotations)
