Any one of the methods below will retrieve proteins with similar domain architectures, which have been identified using the Conserved Domain Architecture Retrieval Tool (CDART):

	Method 1:		Use the CD-Search tool to compare a protein query sequence (either as raw sequence data in FASTA format, or as a GI or Accession) against the desired conserved domain data set, in order to identify functional units within the query sequence. Then press the "Search for similar domain architectures" button on the search results page. (See #1a and 1b in the example below.)
	Method 2:		Retrieve a sequence record of interest from Entrez Protein database, open its "Links" menu, and select "Domain Relatives." (See #2 in the example below.)
	Method 3:		Enter a protein query sequence (either as raw sequence data in FASTA format, or as a GI or Accession) directly on the Conserved Domain Architecture Retrieval Tool (CDART) page.
