EFI - Genome Neighborhood Tool

This web resource is supported by a Research Resource from the National Institute of General Medical Sciences (R24GM141196-01).

The tools are available without charge or license to both academic and commercial users.

Reorganization of UniProtKB

With the current 2026_02 release, the UniProtKB database is reorganized to include an expanded number of Reference Proteomes to better capture biodiversity. This includes the removal of proteins from taxonomically unclassified organisms, i.e., those without a binomial species name (genus and species). The total number of accessions in UniProtKB has been reduced from 253,635,358 in the “legacy” 2025_03 release to 149,810,139 in the current 2026_02 release.

We are providing the option to select either the “legacy” 2025_03 database or the current UniProtKB database (now 2026_02) when generating SSNs. You can select the database in the “Database” accordion on the pages for the EFI-EST options, the EFI-GNT tool, and the Taxonomy Tool. We suggest that you compare the SSNs, GNNs, and GNDs generated from both databases as you explore the information you are seeking.

Update of EFI Tools

The EFI Tools are being upgraded on 10/21/26. While the updated site is functionally identical to the old site, jobs run prior to that date will only be available through the results link in the finalization email (not the Previous Jobs tab). User accounts created on the old site will no longer be available, and users are encouraged to create new accounts when the upgraded site becomes available.

Colored Sequence Similarity Network (SSN)

Each cluster in the submitted SSN has been identified and assigned a unique number and color. Node attributes for "Neighbor Pfam Families" and "Neighbor InterPro Families" have been added.

Genome Neighborhood Networks (GNNs)

GNNs provide a representation of the neighboring Pfam families for each SSN cluster identified in the colored SSN. To be displayed, neighboring Pfams families must be detected in the specified window and at a co-occurrence frequency higher than the specified minimum.

SSN Cluster Hub-Nodes: Genome Neighborhood Network (GNN)

Each hub-node in the network represents a SSN cluster. The spoke nodes represent Pfam families that have been identified as neighbors of the sequences from the center hub.

Pfam Family Hub-Nodes Genome Neighborhood Network (GNN)

Each hub-node in the network represents a Pfam family identified as a neighbor. The spokes nodes represent SSN clusters that identified the Pfam family from the center hub.
