COGs stands for Clusters of Orthologous Genes. The database was initially created in 1997 (Tatusov et al., PMID: 9381173) followed by several updates, most recently in 2014 (Galperin et al., PMID: 25428365). The current update includes complete genomes of 1,187 bacteria and 122 archaea that map into 1,234 genera. The new features include ~250 updated COG annotations with corresponding references and PDB links, where available; new COGs for proteins involved in CRISPR-Cas immunity, sporulation, and photosynthesis, and the lists of COGs grouped by pathways and functional systems.

Pattern for Local Unique Identifiers

Local identifiers in Cluster of orthologous genes should match this regular expression:
^COG\d+$

Example Local Unique Identifier

COG0001   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Cluster of orthologous genes should match this regular expression:
^cog\.cluster:COG\d+$

Example CURIE

cog.cluster:COG0001

The metaregistry provides mappings between the Semantic Farm and other registries. There are 6 mappings to external registries for this resource with 3 unique external prefixes.

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier COG0001 is used to demonstrate the providers available for Cluster of orthologous genes. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.

Additional providers curated in the Semantic Farm are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
