Welcome to Entrez Protein Clusters (ProtClustDB). This collection of related
protein sequences (clusters) consists of Reference Sequence proteins encoded by complete genomes.
This database contains both curated and non-curated clusters. For release-specific information check the
stats page.
The Protein Clusters database provides easy access to annotation information, publications,
domains, structures, and external links and analysis tools including
multiple alignments, phylogenetic trees, and genomic neighborhoods (ProtMap).
Protein Clusters can be searched like any other Entrez database. For more information on how to use
Entrez please examine the Entrez Help Document.
