Do you currently add an organism name(s) to focus your searches when using the BLAST standard nr database? You can now focus your searches by organism with the BLAST ClusteredNR database and get faster results with a better overview of protein homologs in a wider range of organisms. Your searches will be restricted to protein clusters that contain one or more sequences from the organism(s) you add.
ClusteredNR results
A search of the ClusteredNR database (results) using human myoglobin (NP_005359.1) as a query and limited to Cetacea (whales & dolphins) returns clusters containing all the whale myoglobin matches present in a search of standard nr, as well as matches to clusters containing cytoglobin (Figure 1 A). These significant cytoglobin matches are not shown in the standard nr results with the Cetacea limit, which are dominated by matches to proteins from a single species, Physeter catodon (sperm whale) (Figure 1 B).
