About KOMP

The Knockout Mouse Project (KOMP) is a trans-NIH initiative that aims to generate a comprehensive and public resource comprised of mouse embryonic stem (ES) cells containing a null mutation in every gene in the mouse genome. The NIH KOMP initiative aims to:

  1. use gene targeting to make the resource of null alleles, marked with a high utility reporter, preferably in C57BL/6;

  2. support a repository to house the products of this resource as well as an additional repatriation' effort to bring into repositories 1000 of the existing high priority mouse knockouts not already stored in a public repository;

  3. develop improved C57BL/6 ES cells that show robust germline transmission, so that they may be used in a high throughput pipeline in generating this resource; and

  4. implement a data coordination center which will make the status and relevant data of the production effort available to the research community.

Towards those ends, NIH awarded five-year cooperative agreements totaling up to $47.2 million to two groups for the creation of the knockout mice lines. Recipients of those awards are Velocigene, a division of Regeneron Pharmaceuticals, Inc., in Tarrytown, N.Y., and a collaborative team from Children's Hospital Oakland Research Institute (CHORI) in Oakland, Calif., the School of Veterinary Medicine, University of California, Davis (UC Davis); and the Wellcome Trust Sanger Institute in Hinxton, England. Under its cooperative agreement, the team led by Pieter deJong, Ph.D., CHORI, along with K. C. Kent Lloyd, D.V.M., Ph.D., UC Davis; and Allan Bradley, Ph.D. FRS, and William Skarnes, Ph.D., at the Wellcome Trust Sanger Institute, plans to systematically create mouse ES cell lines in which 5,000 genes have been knocked out by gene targeting. The VelociGene division of Regeneron, led by David Valenzuela, Ph.D. and George D. Yancopoulos, M.D., Ph.D., will take aim at a different set of 3,500 genes. Both groups will utilize information from the finished mouse genome sequence to design targeting vectors, which will be built by large-scale, automated technologies. The combined collection of mouse ES cells with knockouts in 8,500 genes will be useful for producing knockout mice.

In addition, NIH awarded another five-year cooperative agreement totaling $2.5 million to Mouse Genome Informatics (MGI) to set up a Data Coordination Center for the Knockout Mouse Project. The center will collect information that will allow the research community to track the scheduling and progress of knockout production. The NIH also awarded cooperative agreements to the University of Pennsylvania in Philadelphia and to the Samuel Lunenfeld Research Institute of Mount Sinai Hospital in Toronto to improve the efficiency of methods for creating knockout lines.

Finally, in June 2007, NIH announced it will provide $4.8 million to establish and support a repository for its Knockout Mouse Project. This award is the final component of a more than $50 million trans-NIH initiative to increase the availability of genetically altered mice and related materials. The University of California, Davis (UC Davis) and Children's Hospital Oakland Research Institute (CHORI) in Oakland, Calif., will collaborate to preserve, protect, and make available about 8,500 types of knockout mice and related products available to the research community.
