Before Nucleotide Sequence Submission

Purpose and Significance of Nucleotide Sequence Submission

In many scientific journals, it is required to assign and to describe INSDC accession number for a nucleotide sequence on the research paper. DDBJ is a member of International Nucleotide Sequence Database Collaboration (INSDC).

When you wish to publicize your sequence through DDBJ, and your sequence is acceptable for DDBJ, you can submit your sequence to DDBJ, even if you have no plan to publication of any research paper related to the sequence.

Once released, the nucleotide sequences submitted to INSDC including DDBJ are available for everyone.

If you submit nucleotide sequences to DDBJ, you can get NO priority for patent.

New Submission or Update?

When you wonder your sequence data should be newly submitted or your previous entry should be modified, do not hesitate to contact us at ddbjupdt#64;

Nucleotide Sequence Submission System is a tool only for new submission, so, do not use Nucleotide Sequence Submission System to send your update request. If you need to modify your previous entry, see the link for update request, and contact us at ddbjupdt#64;

Rights and Duties of Submitter

For sequence submission to DDBJ, it is required for submitters to provide not only nucleotide sequence but also address of submitters and contact person, reference(s) (including primary citation), names of source organisms, function, natures of genes, and so on (collectively means "registration information" of the entry).

DDBJ releases its data in the DDBJ flat file format. Submitter(s) and contact person of the entry are indicated in the REFERENCE 1 of DDBJ flat file, in principle

Following the progress of research, personnel change, and/or correction of some error, submitters of the entry can revise and/or update their own nucleotide sequence and registration information.

As mentioned above and the page to explain dataflow, the nucleotide sequences released from DDBJ are available for everyone. When a user other than the submitter of the entry points out some error(s) in the entry, DDBJ will inform it to contact person of the entry. Since only submitters of the entry can revise and/or update the entry, it depends on the submitters of the entry if the entry is modified following user's claim or not.

Basically, it is required for the submitters to response user's inquiry about their own entry. When you wish to contact to the submitter(s) of an entry of your interest, please contact us through the inquiry form with reasons briefly, then we will forward your message to the submitter(s). So, do not block E-mails from DDBJ.

[Caution]Revision of DDBJ flat file format: Deletion of E-mail address, phone and fax numbers

When there is a disagreement between users and submitters on registration information of an entry, DDBJ maintains neutrality for both opinions.

Releases of Primary Citation and Sequence Data

During preparation/submission of primary citation, DDBJ can store your registration information privately in the meantime. If necessary, submitters have to include a hold date in their registration information. Then, the entry with a hold date is stored privately at DDBJ. DDBJ must maintain registration information as confidential until publication of the entry.

The hold data will be open to the public according to principle of data release.

In principle, even submitters cannot remove their own entry if the entry has already been released and/or the accession number is publicized in Journal etc.

However, DDBJ can suppress the entry in many of its services following the submitter's request.
