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".
DEFINITION Zea mays Cat3 gene for catalase, complete cds.
Format: [organism name] [gene name] gene for [product name], complete cds.
DEFINITION Homo sapiens mRNA for glyceraldehyde-3-phosphate
dehydrogenase, partial cds.
Format: [organism name] mRNA for [product name], partial cds.
DEFINITION Saccharomyces cerevisiae gene for 25S rRNA, partial
sequence.
Format: [organism name] gene for [product name], partial sequence.
partial sequence; this sequence is partial
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], ...... genes for [product name], ......., complete cds.
DEFINITION Homo sapiens cDNA, clone:ABC123, 3' end, expressed
in brain.
Format: [organism name] cDNA, clone:[clone name], [other information].
The clone name is mandatory.
DEFINITION Mus musculus DNA, clone:1H11A14, 1q region.
Format: [organism name] DNA, clone:[clone name], [other information].
The clone name is mandatory.
DEFINITION TPA_exp: Homo sapiens GAPD mRNA for
glyceraldehyde-3-phosphate dehydrogenase, complete cds.
In the case of TPA (Third Party Annotation), either of "TPA_exp:" (for TPA:experimental) or "TPA_inf" (for TPA:inferential) is described at the beginning of DEFINITION.
DEFINITION Mus musculus mRNA, 1 month adult cerebellum RIKEN Cap Analysis
Gene Expression (CAGE) library.
Organism name, molecular type, developmental stage, tissue, cell, method of producing sequence and else are described.
In most cases of MGA, EST, GSS data, the contents of "DEFINITION" is prepared by the submitter, not by the databank.
