CDD 2.17

[04-Jun-2009]  The CDD 2.17 release includes 484 new NCBI-curated domains, as well as records from a new data source, TIGRFAM, and protozoan domains from the Protein Clusters (PRK) database.

 

Specific Hits

[08-May-2008]  The CD-Search tool now shows four types of hits in search results, including specific hits. A specific hit is a high confidence association between a protein query sequence and a conserved domain, resulting in a high confidence level for the inferred function of the protein query sequence. more...

 

Superfamilies

[08-May-2008]  The Conserved Domain Database (CDD) is now organized into superfamilies. A superfamily cluster is a set of conserved domain models that generate overlapping annotation on the same protein sequences. These models are assumed to represent evolutionarily related domains and may be redundant with each other. more...
