Alias

An alias is a gene identifier from an outside organization or database. Inside the NMPDR's data structures, the FIG ID is used for each gene. Each gene also has a list of aliases. There may be none, or there may be a dozen.

Refseq IDs are included without change, but most of the other aliases use a prefix to identify the type. The prefix ends with either a vertical bar (|) or colon (:). For example, the gene with a FIG ID of fig|100226.1.peg.3361 has the following aliases.

• GeneID:1098838, its Gene ID
• gi|21221828, its Genbank ID
• kegg|sco:SCO3401, its KEGG ID
• NP_627607.1, its Refseq ID
• LocusTag:SCO3401, its locus tag
• tr|Q9X8I1, its TREMBL ID
• uni|Q9X8I1, its UniProt ID

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