The Feb. 2003 mouse (Mus musculus) genome assembly is based on NCBI Build 30.

Sample position queries

A genome position can be specified by the accession number of a sequenced genomic clone, an mRNA or EST or STS marker, or a cytological band, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list provides examples of various types of position queries for the mouse genome. See the User's Guide for more information.

   Genome Browser Response:

chr16   Displays all of chromosome 16
chr16:1-5000000   Displays first 5 million bases of chr 16

D16Mit120   Displays region around STS marker DMit16120 from the MGI consensus genetic map. Includes 100,000 bases on each side as well.
D16Mit203;D16Mit70   Displays region between STS markers D16Mit203 and D16Mit70. Includes 100,000 bases on each side as well.
AW045217   Displays region of EST with GenBank accession AW045217
Ncam2   Displays region of genome with official MGI mouse genetic nomenclature Ncam2

pseudogene mRNA   Lists transcribed pseudogenes but not cDNAs
zinc finger   Lists many zinc finger mRNAs
kruppel zinc finger   Lists only kruppel-like zinc fingers
huntington   Lists candidate genes associated with Huntington's disease
Xu,C.S.   Lists mRNAs deposited by co-author C.S. Xu

Use this last format for author queries. Although GenBank requires the search format Xu CS, internally it uses the format Xu,C.S..


Assembly details

This assembly is a composite version constructed using with the MGSCv3 Whole Genome Shotgun assembly and high throughput genomic sequence (HTGS). The UCSC mm3 assembly contains only the reference strain C57BL/6J.

Build 30 includes 705 megabases of finished sequence, compared with 96 megabases of finished sequence in the previous assembly. For more information about this version, see the NCBI assembly notes and Build 30 statistics.

The mm3 sequence and annotation data may be downloaded from the UCSC Genome Browser FTP server or Downloads page.

Many people in the Mouse Genome Sequencing Consortium contributed to this assembly. The Sanger Institute in particular contributed a large amount of finished sequence. Richa Agarwala, Deanna Church, and coworkers at NCBI layered the finished clones on top of the Arachne whole genome shotgun assembly. Arian Smit constructed a new RepeatMasker library. The mm3 tracks were generated by UCSC and collaborators worldwide. See the Credits page for a detailed list of the organizations and individuals who contributed to the success of this release.
