Tsc2
Name: TSC complex subunit 2
Synonyms: tuberin, Nafld, tuberous sclerosis 2
Type: Gene
Species: Mouse
Chromosome: 17
Alteration at locus: Conditional
NCBI: 22084
VEGA: 17
Homologene: 462
Genetic Alterations
A loxP and a loxP-neo-loxP cassette flanked exon 3 of Tsc2 which consists of 111 bp, encoding 37 amino acids near the N terminus of the protein (note that in some schemes this is counted as exon 4; however in accordance with human TSC2 gene, it is denoted this as exon 3, labeling a 5' untranslated exon as 1a). The neo cassette was removed in ES cells by transient cre expression leaving exon 3 floxed.
Genotype Determination
ES Cell Line
J1 derived from 129S4/SvJae
Phenotype

Homozygous: No observable phenotype. 

Heterozygous: No observable phenotype. 

Expected Phenotype when Cre-excised: For Cre-excision, mice bearing the conditional allele were subsequently bred to a nestin-cre allele, in which recombination occurs in the germline, to derive mice with the deleted allele. The phenotype depends on the organ in which excision is induced resulting in an exon 3 deleted allele. Homozygous cre-excised phenotype is embryonic lethal. Heterozygous cre-excised mice exhibit tumors in multiple tissues.

Strain Development

The construct was electroporated into J1 ES cells derived from 129S4/SvJae. One ES clone was subjected to transient cre expression to derive subclones in which the neo cassette had been eliminated by recombination and injected into blastocysts. Chimeric offspring were bred to C57BL/6 to found a conditional allele colony.

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.
