The information of references related to the submitted sequence is indicated on REFERENCE line (other than REFERENCE 1). Since REFERENCE 2 indicates the publication status of the sequence, the reference which does not describe about the submitting sequence is indicated as REFERENCE 3 or after, not as REFERENCE 2.
When DDBJ notices a paper publication with an accession number, DDBJ will update the entry with the accession number, if necessary. During the process of the update, the prepublication paper(s) described in the line(s), REFERENCE 2 and/or later, will be revised without any notice to submitters, if applicable;
i.e. When the submitted data, submitters' affiliation, author names, title, and journal name of the prepublication paper, are enough reasonable to be revised.
