Do you submit eukaryotic nuclear mRNA sequences to GenBank? A new mRNA submission wizard is available! Built on the modern Submission Portal framework, this new wizard will bring you an enhanced experience, including:
Guided submission experience specific for mRNA sequences
Automated trimming of vector and removal of short sequences
Easier input for source metadata
New feature annotation web forms for coding region (CDS) and untranslated region (5’ UTR, 3’ UTR)
Extensive feature previews (Figure 1)
Faster sequence processing and accession assignment
Access to a fix error workflow prior to accession assignment
Do you need a quick way to annotate features on a similar set of sequences for your GenBank submission? You can now submit sequences from the same region or gene in an alignment format in BankIt and use the new ‘Feature propagation option’ (Figure 1) to apply features from a single sequence to other aligned sequences. You simply annotate one sequence and then copy that annotation across all the sequences in your submission.
Here’s how you can propagate features in three easy steps:
The 2018 Nucleic Acids Research database issue features several papers from NCBI staff that cover the status and future of databases including CCDS, ClinVar, GenBank and RefSeq. These papers are also available on PubMed. To read an article, click on the PMID number listed below.
Submitting sequences to GenBank can seem complicated at first, but starting with a solid foundation in the form of a properly formatted file will make the process go smoothly.
Before submitting sequence data to GenBank, the data must be formatted correctly, the most common file format being FASTA. This post will show you how to create a FASTA file for submitting single- and multiple-nucleotide sequences.
Submitters can upload FASTA-formatted sequence files using NCBI’s stand-alone software Sequin, command line tbl2asn or our web-based submission tool BankIt.
The image below depicts a single sequence in FASTA format. For multiple sequences, such as those of population or phylogenetic studies, environmental samples, and batch sequences of the same gene, create the file using the steps below and put the set of sequences together in a single FASTA file.
