T1 CDART: Protein Homology by Domain Architecture JF Genome Research JO Genome Research YR 2002 FD October 01 VO 12 IS 10 SP 1619 OP 1623 DO 10.1101/gr.278202 UL http://genome.cshlp.org/content/12/10/1619.abstract AB The Conserved Domain Architecture Retrieval Tool (CDART) performs similarity searches of the NCBI Entrez Protein Database based on domain architecture, defined as the sequential order of conserved domains in proteins. The algorithm finds protein similarities across significant evolutionary distances using sensitive protein domain profiles rather than by direct sequence similarity. Proteins similar to a query protein are grouped and scored by architecture. Relying on domain profiles allows CDART to be fast, and, because it relies on annotated functional domains, informative. Domain profiles are derived from several collections of domain definitions that include functional annotation. Searches can be further refined by taxonomy and by selecting domains of interest.
