Genetic Alterations

These MDMUT-Gata2 knock-in (KI) mice have a CRISPR-generated insertion of a mutated cyclin B1 (Ccnb1) mitotic degradation (MD) domain sequence after the start codon in exon 2 of the GATA binding protein 2 (Gata2) gene. The mutated Ccnb1 MD sequence inactivates the domain and leads to stable GATA2 protein expression throughout the cell cycle. This MDMUT-Gata2 KI model was generated as a control for the MD-Gata2 mouse line (Stock No. 071768).

ES Cell Line
Not specified
Phenotype
GATA2 is a zinc-finger transcription factor involved in regulating hematopoiesis and Cyclin B1 is a kinase that is necessary for cell cycle M-phase transition. These MDMUT-Gata2 knock-in (KI) mice have a CRISPR-generated insertion of a mutated cyclin B1 (Ccnb1) mitotic degradation (MD) domain sequence after the start codon in exon 2 of the GATA binding protein 2 (Gata2) gene. The point mutation in the Ccnb1 MD results in an arginine to alanine (R42A) substitution; the mutation in the MD sequence inactivates the domain and leads to stable GATA2 protein expression throughout the cell cycle. This MDMUT-Gata2 KI model was generated as a control for the MD-Gata2 mouse line (Stock No. 071768).

Homozygous MD-Gata2 KI mice are viable and fertile with no overt phenotype. These mice may be used as controls for the MD-Gata2 mice (Stock No. 071768) when studying the role of GATA2 in hematopoiesis.

Strain Development
The MDMUT-Gata2 knock-in (KI) allele was generated using CRISPR/Cas9 endonuclease-mediated genome editing. A guide RNA (GACACAGTAGTGGACCATGGAGG) was used to introduce a mutated (R42A) mitotic degradation (MD) domain sequence of cyclin B1 (Ccnb1) inserted after the start codon in exon 2 of the GATA binding protein 2 gene (Gata2) on chromosome 6 (ENSMUSG00000015053). The gRNA was cloned in plasmid pX458 (Addgene; Cat#48138) that co-expresses GFP and Cas9 together with the gRNA. The homologous repair template used was a dsDNA construct where the mutated MD (MDMUT) sequence is flanked by 800bp homology arms. GFP-positive cells were sorted by FACs 48h later and plated, 6 days later individual ESC colonies were picked, expanded and genotyped. Two independent MDMUT-Gata2-positive (C57BL/6N x 129S) F1 embryonic stem cell clones where then microinjected into 8-cell C57BL/6NRj morulae to generate chimeras. Correctly targeted pups were identified by PCR and sequencing. The resulting MDMUT-Gata2 KI mice were bred to C57BL/6NRj (Janvier Labs) mice for at least 1 generation by the donating laboratory. To establish our live colony, an aliquot of frozen sperm was used to fertilize C57BL/6NJ oocytes.

Order Request Information

Limited quantities of breeder mice (up to 2 males and 2 females or 4 mice) per investigator per month are available from a live colony, usually available to ship in under 12 weeks. Larger quantities may be available, please contact the distributing center directly at csmmrrc@jax.org for more details.

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.
