Strain Information

Rack1tm1.1Cart
Name: receptor for activated C kinase 1; targeted mutation 1.1, Christine A Cartwright
Synonyms: Rack1fl
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 11
Alteration at locus: Targeted Mutation
Rack1
Name: receptor for activated C kinase 1
Synonyms: p205, GB-like, Gnb2-rs1, Gnb2l1
Type: Gene
Species: Mouse
Chromosome: 11
Alteration at locus: Targeted Mutation
NCBI: 14694
HGNC: HGNC:4399
Homologene: 4446
Genetic Alterations
Two loxP sequences have been place in the gene to flank exon 2. Deletion of exon 2 will result in a frameshift and pre-mature termination of Rack1 translation.
Genotype Determination
ES Cell Line
R1 derived from (129X1/SvJ x 129S1/Sv)F1-Kitl+
Phenotype
The strain was generated to conditionally knockout Rack1 gene in the presence of the Cre recombinase. The strain by itself does not have a phenotype, which is as desired. When the floxed Rack1 was bred with the vil-cre-ER mice to generate an inducible intestinal Rack1 KO, the mice lost weight, developed diahrea and die between 1 to 2 week after the mice were given tamoxifen to induce Cre activity.
Strain Development
A targeting vector with exon 2 of Rack1 and the neomycin resistance gene floxed was linearized and electroporated into R1 embryonic cells, clone E1 was transfected with a Cre-expressing plasmid pOG231-Cre to remove the neomycin resistance gene. Clone E1F3 was then used for microinjection and chimera were mated to C57BL/6 females for germline-derived F1 mice. F1 mice were mated to C57BL/6J for colony expansion.
Suggested Control Mice
Rack1-expressing littermate controls.
MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@ucdavis.edu. Older strains may not have this information.

Colony and Husbandry Information

Colony Surveillance Program and Current Health Reports

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc@ucdavis.edu.
The MMRRC at UC Davis performed microbita analysis on feces samples received from the donating investigator while the mice were still at their facility. There is a MMRRC Fecal Microbiota report available for this strain.If you are interested in having the MMRRC at UC Davis perform microbiota analysis once the line is established at your facility please contact mmrrc@ucdavis.edu.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to mmrrc@ucdavis.edu for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

Litter Recovered litter4; additional fees for any special requests.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
