Alias

An alias is an alternative gene identifier, such as an accession number from another database (sometimes called a dbxref), a locus tag, or a gene name. Inside the NMPDR's data structures, the FIG ID is used for each gene. Each gene also has a list of aliases that can be used to search for it. There may be none, or there may be a dozen.

Beginning in 2008, the Protein Information Resource has been curating identifiers for genes in the NMPDR and other major genetic databases. The table below shows the IDs that have been processed by this effort. These IDs are the primary source of aliases found in the Sprout Database. Any one of them can be used in place of the FIG ID to specify the gene name in the NMPDR Banner search box, in Batch Search ID files, or as gene names for the Gene BBH Search.

ID Type Count
CMR 1,176,418
NCBI 3,587,361
RefSeq 1,412,423
UniProt 2,908,264

Displaying alternate IDs for a gene
You can find the list of curated IDs on the annotation overview page. Simply click the show button next to the database cross references heading to see the IDs. Each one will link to the gene's page on the other database's web site. The aliasing process is not exact. Some genes are called differently in the various databases, and a single gene in the Sprout Database could correspond to more than one in NCBI or RefSeq.

In addition to these curated aliases, we attempt to find other identifiers and add them to the database. These include gene identifiers such as dnaK or luxR, accession keys, and locus tags. The following is the list of these extra aliases for fig|100226.1.peg.3361.

  • GeneID:1098838 (Gene ID)
  • SCO3401, (locus tag)
  • gi|21221828, (GenBank ID)
  • *kegg|sco:SCO3401 (KEGG ID)
  • *tr|Q9X*I1 (Trembl ID)

Gene names (e.g. dnaK or grpE) are also considered aliases.

To see a complete list of the aliases, included the non-curated IDs, go to the word search page, check the Show Alias Links box, and type in the gene's ID. The list of aliases will be in the rightmost column. As a convenience, we've also provided a form on this page. Simply enter the gene's ID, click the button, and if it's in our database, you'll be able to see its aliases.
