Species: Mus musculus (mouse)
Chromosome: 6
Alteration at locus: Targeted Mutation
Ezh2
Name: enhancer of zeste 2 polycomb repressive complex 2 subunit
Synonyms: Enx-1, Enx1h, KMT6
Type: Gene
Species: Mouse
Chromosome: 6
Alteration at locus: Targeted Mutation
NCBI: 14056

Genetic Alterations
Two loxP sites were introduced into Ezh2 locus between exons 15-16 and 19-20. In this way the loxP sites are flanking the Exons 16-19, which encode the essential SET domain of Ezh2 protein.
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line
    E14 derived from 129P2/OlaHsd
    Phenotype
    Homozygous: Inactivation of Ezh2 in BM stem cells causes developmental block of both B and T cells. Inactivation of Ezh2 in germline leads to embryonic lethality. Inactivation of Ezh2 in peripheral T cells shows defective TCR mediated signaling.

    Heterozygous: Same as wild-type

    Allelic Composition: Ezh2tm1Tara/Ezh2tm1Tara (Genetic Background: involves: 129P2/OlaHsd )

    Strain Development

    Conditional Ezh2 locus (Ezh2 fl/fl) was generated using E14.1 ES cells. Neo cassette was removed in vitro by transient expression of pIC-Cre. The targeted ES cells were injected into CB20 blastocysts to generate chimera mice, which were crossed to C57BL/6 mice. Germline transmittion of targetted allele was scored by coat color and genotyping.

    A sample from this MMRRC strain was analyzed using the Mouse Universal Genotyping Array (MUGA) and MMRRC computational tools were used to assess the genetic background. A summary of the data can be found here.

    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_health@med.unc.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@med.unc.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.

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

    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.
