The GenBank sequence database is an open access, annotated collection of publicly available nucleotide sequences and their protein translations. GenBank is part of the International Nucleotide Sequence Database Collaboration (INSDC) and is produced and maintained by the National Center for Biotechnology Information (NCBI), a division of the United States National Library of Medicine (NLM), part of the National Institutes of Health (NIH).
As of GenBank release 271.0 (April 2026), the database contained 53.90 trillion bases and 6.27 billion sequence records, including 261,460,182 GenBank entries containing 7,289,942,983,522 base pairs of sequence data. The database includes sequences from more than 581,000 formally described species. The database was established in 1982 by Walter Goad and the Los Alamos National Laboratory and has become a central resource for biological research. GenBank is built from direct submissions by individual laboratories as well as bulk submissions from large-scale sequencing projects.
