  About the UCSC Genome Bioinformatics Site

Welcome to the UCSC Genome Browser website. This site contains the reference sequence and working draft assemblies for a large collection of genomes. It also provides portals to ENCODE data at UCSC (2003 to 2012) and to the Neandertal project. Download or purchase the Genome Browser source code, or the Genome Browser in a Box (GBiB) at our online store.

We encourage you to explore these sequences with our tools. The Genome Browser zooms and scrolls over chromosomes, showing the work of annotators worldwide. The Gene Sorter shows expression, homology and other information on groups of genes that can be related in many ways. Blat quickly maps your sequence to the genome. The Table Browser provides convenient access to the underlying database. VisiGene lets you browse through a large collection of in situ mouse and frog images to examine expression patterns. Genome Graphs allows you to upload and display genome-wide data sets.

The UCSC Genome Browser is developed and maintained by the Genome Bioinformatics Group, a cross-departmental team within the UC Santa Cruz Genomics Institute and the Center for Biomolecular Science and Engineering (CBSE) at the University of California Santa Cruz (UCSC). If you have feedback or questions concerning the tools or data on this website, feel free to contact us on our public mailing list.

The Genome Browser project team relies on public funding to support our work. Donations are welcome -- we have many more ideas than our funding supports! If you have ideas, drop a comment in our suggestion box.

03 March 2015 - Use UDR for Quick Sizable Downloads

The UCSC Genome Browser is pleased to share a download protocol to use when downloading large sets of files from our download servers: UDR (UDT Enabled Rsync). UDR utilizes rsync as the transport mechanism, but sends the data over the UDT protocol, which enables huge amounts of data to be downloaded efficiently over long distances.

Protocols like http, ftp and rsync can have a problem in that the further away the download source is from the user, the slower the speed becomes. Protocols like UDT/UDR allow for many UDP packets to be sent in batch, thus allowing for much higher transmit speeds over long distances. UDR will be especially useful for users who are downloading from places that are far away from California. The US East Coast and the international community will likely see much higher download speeds by using UDR rather than rsync, http or ftp. Read more.

26 February 2015 - New Training Video!

Ever wondered how to find the tables associated with your favorite Browser track? Find out how in our new training video. See our training page, our YouTube channel, and our blog for details.

12 February 2015 - Blat Your Assembly Hub: Assembly data hubs, track hubs that allow researchers to annotate genomes that are not in the UCSC Genome Browser, can now use blat to quickly find DNA and protein sequences in their unique assemblies. Read more.

11 February 2015 - dbSNP 142 Available for hg19 and hg38: We are pleased to announce the release of four tracks derived from NCBI dbSNP Build 142 data, available on the two most recent human assemblies GRCh37/hg19 and GRCh38/hg38. The new tracks contain a substantial amount of additional annotation data not included in previous dbSNP tracks, with corresponding coloring and filtering options in the Genome Browser. Read more.

2 February 2015 - Host a Genome Browser Workshop: New timeslots are now available to host a Genome Browser workshop at your institution. Read more.
