New Gene Information from the Alliance of Genome Resources

NCBI Gene now has descriptive information about genes from the Alliance of Genome Resources for organisms including Caenorhabditis elegans, Danio rerio, Drosophila melanogaster, Homo sapiens, Mus musculus, Rattus norvegicus, and Saccharomyces cerevisiae.

Figure 1. The gene summary section of the Drosophila melanogaster slmb Gene Full Report showing the link to the corresponding record at the Alliance of Genome Resources.

The Summary section of the Gene Full Report page has Links to gene pages at the Alliance of Genome Resources (Figure 1). These are also in the right-hand sidebar of the Links to other resources section.   In the case of genes that don’t have a RefSeq summary,  we use  the textual gene descriptions from the Alliance of Genome resources.

The Drosphila slmb gene record shows the enhancements provided by the Alliance of Genome Resources.  The gene_info.gz files on the  Gene FTP site also include AllianceGenome references in the dbXrefs column.

New NCBI Gene Ensembl Comparison Expansion

NCBI Gene has added Ensembl Rapid Releases to the calculation of matching annotations between NCBI RefSeq and Ensembl. This has resulted in the inclusion of over 60 additional assemblies for a total of 241 organisms represented in the set. Matches are made based on transcript and CDS comparisons, and Ensembl gene, transcript, and protein identifiers for annotations similar to the NCBI RefSeq annotations are reported in NCBI Gene and in the gene2ensembl file on the Gene FTP site. The Ensembl annotation is also available in the graphical view and in NCBI’s Genome Data Viewer to give you a side-by-side view of how the annotations compare. Check out blue whale E2F1 for an example.

New NCBI Datasets home and documentation pages provide easier access

NCBI Datasets, the new set of services for downloading genome assembly and annotation data (previous Datasets posts), has redesigned and reorganized web pages to make it easier to find and access the services and documentation you need.

NCBI Datasets has a fresh new homepage (Figure 1) highlighting the types of data available through our tools. Available data include genome assemblies, genes, and SARS-CoV-2 genomic and protein data.  You can easily access these from the new page or learn more with our new documentation pages.

Figure 1. Features of the new Datasets homepage with quick access to help documentation including the Quickstart and How-to guides as well as access to Genome, Gene, and Coronavirus Data, and the Datasets and Dataformat command-line tools.

The Datasets command-line tool now provides ortholog data

You can now get gene ortholog data using the NCBI Datasets command-line tool using a gene ID, gene symbol, or RefSeq nucleotide or protein accession. Data are available for vertebrates and insects. The vertebrate orthologs includes a specialized set for fish.  (See our recent post for more information on the orthologs for fish and insects.)

You can retrieve metadata for gene orthologs in JSON Format, or you can download a compressed (zip) archive containing both metadata and sequences (Figure 1).

Figure 1. Command-lines  that use a gene symbol (BRCA1) to retrieve mammalian ortholog metadata (top, JSON metadata shown in part in the image) and sequences (bottom).

Announcing the RefSeq annotation of rat mRatBN7.2!

Announcing the RefSeq annotation of rat mRatBN7.2!

NCBI RefSeq has finished its initial annotation of the new rat reference assembly, mRatBN7.2, recently released by the Darwin Tree of Life Project at the Wellcome Sanger Institute. This is the first coordinate-changing update to the rat reference since the 2014 release of Rnor_6.0 from the Rat Genome Sequencing Consortium and brings the rat assembly into the modern age with a nearly 300x increase in contig N50 and 9x increase in scaffold N50 lengths. It’s a major improvement!

Programmatic access to Gene data using Datasets command-line and API

In March, we announced NCBI Datasets, a new resource that lets you easily retrieve and download data from across NCBI databases. Did you know you can now fetch NCBI Gene data programmatically using the NCBI Datasets API or command-line tool?  Quickly retrieve both metadata and gene sequence data for multiple Gene records including transcripts and proteins in one shell command or API request. The API documentation is a good way to get started with programmatic access (Figure 1).

Figure 1. The Datasets API documentation showing a demonstration retrieving Gene metadata using RefSeq mRNA accessions. The API returns a readily processed JSON object.

NCBI Datasets now provides downloads of gene data for more than 30 thousand organisms

NCBI Datasets now offers Gene tables: customizable tables of the genes you specify, with key gene information, and the ability to easily download a dataset of genomic, transcript and protein sequences.

Drag and drop a list of Gene IDs or gene symbols, and the data table shows your genes with up to 15 columns of metadata, including genomic coordinates, RefSeq transcript and protein accessions, Ensembl IDs and UniProt accessions, and other gene information. You can browse and select items in your table on the web, or download everything to your computer for later analysis (Figure 1).

Figure 1. The Data tables web download. Top panel. Enter or upload a list of gene identifiers or symbols. Bottom panel. The resulting table display allows you to browse results, download the table or the sequence data for the genes (genomic, transcripts, proteins).  Continue reading “NCBI Datasets now provides downloads of gene data for more than 30 thousand organisms”

The latest in COVID-19 related human gene annotation now in NCBI RefSeq and Gene

Interested in human genes involved in COVID-19 biology? NCBI’s RefSeq group has been hard at work compiling a set of human genes with roles in coronavirus infection and disease. You can now see and search for these genes and their regulatory elements in NCBI Gene and RefSeq.

Figure 1. Top section of the human ACE2 record in the Gene database. COVID-19 information can be found in the Summary and Annotation information sections.
