Felis catus (NHGRI Press Photos)

The March 2006 Felis catus draft assembly (Broad Release 3) was produced by the Broad Institute of MIT/Harvard and Agencourt Bioscience (now a part of Beckman Coulter Genomics).

### Sample position queries

A genome position can be specified by the accession number of a sequenced genomic region, an mRNA or EST, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the F. catus genome. See the User's Guide for more information.

pseudogene mRNA |  | Lists transcribed pseudogenes, but not cDNAs
homeobox caudal |  | Lists mRNAs for caudal homeobox genes
zinc finger |  | Lists many zinc finger mRNAs
kruppel zinc finger |  | Lists only kruppel-like zinc fingers
benson |  | Lists mRNAs deposited by scientist named Benson

Use this last format for author queries. Although GenBank requires the search format Ohno K, internally it uses the format Ohno,K..

### Assembly details

The genome has been sequenced to 2X coverage and consists of 217,790 scaffolds. The total contig length for this assembly is approximately 1.6 Gb spanning nearly 4.0 Gb (with 60.1% in gaps). There are 749,376 contigs, with an N50 length of 2,506 bases. There are 149,283 supercontigs, with an N50 length of 49,769 bases (not including gaps). The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer.

Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page. These data have specific conditions for use.

The F. catus browser annotation 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.
