Description

Strain Information

Type Mutant Stock; Targeted Mutation; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse   Donating Investigator David Garbers,   U.T. Southwestern Medical Center

Description
Homozygotes are viable. Males, but not females, are completely infertile. The targeted mutation fails to significantly alter sperm production, protein tyrosine phosphorylation associated with capacitation, induction of the acrosome reaction, forward velocity or percentage of motility. Sperm cells fail to acquire hyperactivated motility associated with penetration of the extracellular matrix of the egg. SDS/PAGE and immunoblotting of total sperm protein were used to confirm the absence of gene product. This strain may be useful in studies of male fertility.

Development
A targeting vector was designed to replace exons 2-5 of the gene with a neomycin drug resistance cassette. The vector was electroporated into 129S6/SvEvTac-derived SM1 embryonic stem (ES) cells. Chimeric mice were generated and backcrossed once to C57BL/6 to produce heterozygotes.

      assigned by genotype

Catsper2^tm1Gar/Catsper2^tm1Gar

        involves: 129S6/SvEvTac * C57BL/6J

• reproductive system phenotype
• asthenozoospermia (MGI Ref ID J:86972)
  • though sperm exhibited normal forward velocity and percentage of motile cells, sperm was unable to generate the hyperactive form of motility necessary for fertilization
• male infertility (MGI Ref ID J:86972)

The following phenotype information may relate to a genetic background differing from this JAX^® Mice strain.

Catsper2^tm1Gar/Catsper2^tm1Gar

        involves: 129S6/SvEvTac

• reproductive system phenotype
• abnormal sperm physiology (MGI Ref ID J:116406)
  • calcium-selective pH sensitive sperm current (I_CatSper) is not detectable
• abnormal sperm motility (MGI Ref ID J:116406)
  • percent motility of mutant sperm decreases more rapidly than wild-type
• asthenozoospermia (MGI Ref ID J:116406)
  • after 90 minutes in viscous conditions, sperm lose their motility compared to wild-type which move more vigorously than initially

Supply Details

Standard Supply

Repository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.

Supply Notes

Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845. This strain is included in the Induced Mutant Resource Colony collection.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX^® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX^® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX^® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
