Genetic Alterations

These Gakflox mutant mice possess loxP sites flanking exon 1 of the cyclin G associated kinase (Gak) gene. GAK functions as a cochaperone with Hspa8 (Hsc70). GAK is involved in the process of clathrin-mediated endocytosis and is critical to development.

Phenotype
These Gakflox mutant mice possess loxP sites flanking exon 1 of the cyclin G associated kinase (Gak) gene. GAK, a cyclin-dependent protein kinase, is a multidomain protein that functions as a cochaperone with Hspa8 (Hsc70). GAK is involved in the process of clathrin-mediated endocytosis and is critical to development. Mice that are homozygous for this allele are viable and fertile. When bred to mice that express tissue-specific Cre recombinase, resulting offspring will have a null allele in the cre-expressing tissues.

For example, when bred to mice carrying Tg(Nes-Cre)1Kln, neuronal Cre recombinase expression results in early lethality and a failure of neuroprogenitor cells to proliferate.

When bred to mice carrying Tg(Alb-cre)21Mgn, Cre recombinase expression in the liver results in lethality by day 5, jaundice, disorganized bile ducts, undifferentiated hepatoblasts, fragmented Golgi and failure to accumulate glycogen.

When bred to adult mice carrying Tg(CAG-cre/Esr1*)5Amc, tamoxifen-inducible cre-recombinase expression results in death within days of tamoxifen treatment.

When bred to mice carrying Tg(KRT14-Cre)1Amc, Cre recombinase expression results in the epidermis, results in postnatal lethality, a defective epidermal barrier and failure to differentiate epidermal layers.

Strain Development
The targeting vector contains a loxP site followed by exon 1 and loxP-flanked PGK neomycin cassette. The construct was electroporated into 129S6/SvEvTac-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to C57BL/6 mice once and then maintained by sibling mating.

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 csmmrrc@jax.org. Older strains may not have this information.

Colony and Husbandry Information

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-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 csmmrrc@jax.org.

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 csmmrrc@jax.org 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.

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.
