RefSeq Release 206 is now available. This release includes the following:
Updated human genome Annotation Release 109.20210514
Updated Annotation Release 109.20210514 is an update of NCBI Homo sapiens Annotation Release 109. The annotation report is available here. The annotation products are available in the sequence databases and on the FTP site.
NCBI staff will be presenting virtual posters at the Cold Spring Harbor Laboratory Biology of Genomes Meeting, May 11 -14, 2021. The posters will cover the following topics: 1) a cloud-ready suite of tools (PGAP, RAPT , and SKESA) for assembling and annotating prokaryotic genomes, 2) Datasets — a new set of services for downloading genome assemblies and annotations, and 3) updates on NCBI RefSeq eukaryotic genome annotation, and the Genome Data Viewer (GDV). Read more below for the full abstracts.
NCBI’s genome Assembly has a number of significant improvements!
Assembly records now have a link to Primer-BLAST making it easy to design primers in the context of a specific eukaryote genome assembly. Figure 1 shows the Assembly page for the Genome Reference Consortium Mouse Build 39 (GRCm39) with the link to Primer-BLAST.
Are you a researcher who works on gene biology and are interested in alternative splice patterns in your gene or genes of interest? If so, be sure to explore the intron feature evidence available in graphics views of genome assemblies annotated by NCBI. You can view the NCBI evidence used for calling splice variant for genes, add other intron feature evidence tracks, and use new display and filter options that make it easier to interpret the data .
Figure 1. Graphical view of the monoamine oxidase gene (MAOA, MOAB) region on the human X chromosome showing intron features tracks (‘RNA-seq intron features, aggregate’ and ‘Intropolis RNA-Seq intron features’). Mousing-over an intron feature activates a tooltip that shows details such as the number of reads with the splice site, the location on the chromosome, the length of the intron and the donor and acceptor bases at the splice site. The Intropolis track was added through the search feature of the Configure Tracks menu and configured (bottom menu) so that the features were sorted by strand and filtered so that only features with greater than 500 reads appear.
RefSeq release 204 is now available online, from the FTP site and through NCBI’s Entrez programming utilities, E-utilities.
This full release incorporates genomic, transcript, and protein data available as of January 4, 2021, and contains 262,714,372 records, including 191,411,721 proteins, 35,353,412 RNAs, and sequences from 106,581 organisms. The release is provided in several directories as a complete dataset and also as divided by logical groupings.
