The CDD [2] paper discusses the protein classification component of NCBI’s Entrez query and retrieval system. The RefSeq [3] paper discusses the RefSeq database, which provides a curated, non-redundant collection of genomic, transcripts, and protein sequences. [1]King, C. “The Hottest Research of 2004-05”.
