Strain Information

Gene Details

Taok2Tg(Tyr)2276AOve
Name: transgene lentiviral insertion 2276A, Paul A Overbeek
Synonyms: OVE2276A, OVE#2276A
Type: Transgene
Species: Mus musculus (mouse)
Chromosome: 7
Alteration at locus: Insertion
Genetic Alterations
These OVE2276A (OVE#2276A) mice harbor a mutation created by random insertion of the Tyro-WPRE-FUGW lentiviral transgene (LV2177). Using inverse PCR analysis, the lentiviral integration site was identified in intron 5 of the TAO kinase 2 gene (Taok2) on chromosome 7. The 5'-LTR is linked to the (-) strand of DNA at position 134,022,901 bp [NCB137/mm9; 5'-134,022,901(-)]. The lentivirus is inserted in the antisense orientation relative to the disrupted mouse gene.
Genotype Determination

Strain Description

Phenotype
The donating investigator reports the phenotype of homozygous mice as: smaller than normal.
Strain Development
A lentiviral transgenic approach was used to generate these mice. The Tyro-WPRE-FUGW lentiviral transgene (LV2177) was designed with a mouse tyrosinase minigene (Tyro) and woodchuck hepatitis virus post-transcriptional regulatory element (WPRE) in the FUGW self-inactivating HIV-based lentiviral vector backbone. The Tyro minigene replaced the ubiquitin-c promoter and EGFP sequences originally found in the FUGW lentiviral vector. The Tyro minigene is composed of the mouse Tyr enhancer region (623 bp), promoter region (657 bp), and 1566 bp cDNA sequence (including the stop codon); all in sense orientation relative to the FUGW backbone. There is no polyA site between the Tyro minigene and WPRE sequence. The WPRE sequence functions to enhance the mRNA transcript stability. This packaged lentivirus was injected subzonally (under the zona pellucida) into 1-8 cell stage FVB/N mouse embryos. Expression of the tyrosinase minigene results in melanin synthesis, so founder mice (F0) were identified by inspection for pigmentation. All F0 mice exhibited mosaic pigmentation. Most F0 mice had more than one lentiviral integration site. F0 mice were assigned an OVE number and then bred with FVB/N mice. Pigmented offspring (F1) with different coat colors were designated as subline A, B, C, etc., for each family. F1 mice were bred with FVB/N mice. F2 mice with different coat colors were designated as sublines A-1, A-2, etc., or B-1, B-2, etc. Breeding with FVB/N mice was continued until litters with only one or two different coat colors were obtained. Mice with identical coat colors were then inbred and assessed for the presence or absence of viable homozygotes. Hemizygous mice of line OVE2276A (OVE#2276A) exhibit medium grey coat color. Using inverse PCR analysis, the lentiviral integration site was identified in intron 5 of the TAO kinase 2 gene (Taok2) on chromosome 7. The 5'-LTR is linked to the (-) strand of DNA at position 134,022,901 bp [NCB137/mm9; 5'-134,022,901(-)]. The lentivirus is inserted in the antisense orientation relative to the disrupted mouse gene. Cryopreserved heterozygous embryos were sent to The Jackson Laboratory Repository node of the Mutant Mouse Regional Resource Center (MMRRC-JAX).

MMRRC Genetic QC

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.

Health Status Report

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

Availability Level

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.

Conditions of Distribution

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.

The donor or their institution limits the distribution to non-profit institutions only.

Fees

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.
