1 When indicated as "assessed by MMRRC" ("YES"), please note that the information presented on this strain is to the best of our knowledge correct and up-to-date at the the MMRRC Distribution Center assigned to maintain and distribute this strain. This information is subject to change due to breeding, maintenance, and other actions. Please direct any questions on the information presented in this table to the MMRRC Distribution Center.

2 If an assessment has not been performed by the MMRRC (as indicated by "NO"), investigators may request specific testing for a fee. Requests should be submitted directly to the MMRRC Distribution Center assigned to the management, archiving, and distribution of the strain. A full listing of available testing and analytical services is available at https://www.mmrrc.org/about/services.php.

3 This information may or may not apply to each individual engineered allele (e.g., Cre, FlpO) present in the strain.

4 Recovery refers to thawing, in vitro fertilization (IVF), and/or embryo culture leading to live offspring.

Cse1l
Name: chromosome segregation 1 like
Synonyms: Cas, Capts, 2610100P18Rik, Xpo2
Type: Gene
Species: Mouse
Chromosome: 2
NCBI: 110750
HGNC: HGNC:2431
Homologene: 1006
Genetic Alterations
loxP sites oriented head-to-tail flank exon 3 of the Cse1l gene to create a conditional allele amenable to Cre-induced recombination.
ES Cell Line
Not applicable
Phenotype
Conditional Cse1l mice do not exhibit a phenotype that differs from the wildtype allele. Following exposure to Cre recombinase under the control of the Sox2 promoter, deletion of exon 3 results in early embryonic lethality with no viable embryos recovered at or beyond early developmental stages. Wnt1-Cre2 mediated conditional deletion in neural crest cells results in embryonic lethality by E11.5 likely due to proliferative defects in the ventricular myocardium. Embryos exhibit severe malformations in the forebrain, midbrain, and hindbrain, accompanied by a dramatic hypoplasia of the frontonasal, maxillary, and mandibular processes, and the second pharyngeal arch. In affected tissues, increased apoptosis is observed during early development, particularly in cranial neural crest-derived regions.

Strain GQC Summary
Gene Specific Genotyping:

To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.

Background Genetic Quality:

The MMRRC has developed a Genetic Quality Control pipeline using the MiniMUGA array to provide additional information to identify and validate genetic backgrounds of MMRRC strains. For more information on whether genetic background data is available, please contact MMRRC_GeneticQC@med.unc.edu. Note: that MiniMUGA genetic background data is not available on all strains, but can be ordered if desired.

Strain Development
CRISPR guide(s) and Cas9 protein were microinjected into C57BL/6NCrl zygotes and progeny were screened for loxP sites flanking exon 3 of the Cse1l gene. Founders were mated to C57BL/6J breeders and derived N1 progeny were identified by PCR and sequencing. Heterozygous N1 mice were intercrossed to produce phenotyping cohorots for 2 generations prior to cryopreservation.

Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain's tissue samples taken when archived by or ordered from the assigned MMRRC Center.

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.

Some MMRRC strains were submitted by the submitter as cryopreserved germplasm, and because these strains were not cryopreserved by the MMRRC, we have not assessed the quality, nor genotype, of this material. Our expertise in reviving mice from various qualities of frozen sperm and embryos, using methods like IVF and ICSI, gives us confidence in successful recoveries in most cases. However, due to the uncertain quality of these samples, we'll limit revival attempts to two per order. Additional attempts are available for a fee, on top of standard charges, if requested. It's important to note that some strains may lack the expected mutation, so we can't assure successful order fulfillment until we attempt to revive the strain.

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.
