The definition briefly describes the information of gene(s). "DEFINITION" is constructed by each of the three data banks in accordance with standard rules in principle.However, in the case of EST or GSS submission using Mass Submission System, DDBJ will sometimes ask submitters to construct "DEFINITION".
Sample: complete sequence of maize catalase coding gene
DEFINITION Zea mays Cat3 gene for catalase, complete cds.
- Format: [organism name] [gene name] gene for [product name], complete cds.
- organism name; The scientific name is indicated as the organism name, in principle.
- gene name; the symbol of the gene
- product name; the general name of product
- complete cds; this coding sequence is complete
Sample: partial sequence of human glyceraldehyde-3-phosphate dehydrogenase coding cDNA
DEFINITION Homo sapiens mRNA for glyceraldehyde-3-phosphate
dehydrogenase, partial cds.
- Format: [organism name] mRNA for [product name], partial cds.
- partial cds; this protein coding sequence is partial
- The gene name is omitted, because the submitter did not describe.
Sample: partial sequence of Bacillus 16S rRNA
DEFINITION Bacillus sp. AZ25 gene for 16S rRNA, partial
- Format: [organism name] [strain name] gene for [product name], partial sequence.
- In cases of unidentified species, comparison of intraspecies, and so on, describe name of strain, isolate or some, as identifier.
- partial sequence; this sequence is part of 16S rRNA.
Sample: multiple CDS of rat mitochondrial DNA
DEFINITION Rattus norvegicus mitochondrial genes for cytochrome
c oxidase subunit II, ATPase subunit 6, cytochrome c
oxidase subunit III, partial and complete cds.
- Format: [organism name] [gene name 1], [gene name 2], ... genes for [product name 1], [product name 2], ..., complete cds.
- The gene names and/or product names are subsequently described from 5'to 3' end.
- "partial, complete and partial cds" is abbreviated to "partial and complete cds".
- If some genes have only gene names or product names, only gene name or product name is described principally.
- If the "DEFINITION" is too long, some information, such as map position, is described instead of the gene or product names.
- Sometimes gene cluster or operon name is described, if it is considered reasonable.
Sample: EST data of human liver 3' end
DEFINITION Homo sapiens cDNA, clone:ABC123, 3' end, expressed
- Format: [organism name] cDNA, clone:[clone name], [other information].
- The clone name is mandatory.
Sample: GSS data of mouse chromosome 1q
DEFINITION Mus musculus DNA, clone:1H11A14, 1q region.
- Format: [organism name] DNA, clone:[clone name], [other information].
- The clone name is mandatory.
Sample: TPA (Third Party Data) of human GAPD
DEFINITION TPA_exp: Homo sapiens GAPD mRNA for
glyceraldehyde-3-phosphate dehydrogenase, complete cds.
- Format: [TPA header]: [organism name] [gene name] mRNA for [product name], complete cds.
- In the case of TPA (Third Party Data), either of "TPA_exp" (for TPA:experimental) or "TPA_inf" (for TPA:inferential) is described at the beginning of DEFINITION.
