The latest version of the Conserved Domain Database contains 2,128 new or updated NCBI-curated domains and now mirrors Pfam version 32 as well as models from NCBIfams, a collection of protein family hidden Markov models (HMMs) for improving bacterial genome annotation. We have also added fine-grained classifications of the cupin and PBP1 superfamilies. You can find this updated content on the CDD FTP site. Read on for detailed release statistics.
