Strain Information

Kcnd2tm1Jmn
Name: potassium voltage-gated channel, Shal-related family, member 2; targeted mutation 1, Jeanne M Nerbonne
Synonyms: Kv4.2-
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 6
Alteration at locus: Knockout
Kcnd2
Name: potassium voltage-gated channel, Shal-related family, member 2
Synonyms: Kv4.2
Type: Gene
Species: Mouse
Chromosome: 6
Alteration at locus: Knockout
NCBI: 16508
HGNC: HGNC:6238
Homologene: 40828
Genetic Alterations
Exon 1 was replaced with a neomycin cassette, thus eliminating the Kcnd2 coding sequence from the beginning of the N terminus to the middle of the S5 S6 (pore) loop. This approach removed essentially all of the Kv4.2 protein, thereby preventing the generation of mutant/truncated Kv4.2 protein that might, if expressed, exert dominant-negative effects on channels encoded by other Kv4 subfamily members.

Strain Development
Male chimeras were bred with C57BL/6J females for ten generations of heterozygous male mice. After 10 generations, heterozygous males and females were produced and bred together to produce knockout mice.

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@missouri.edu. Older strains may not have this information.

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@missouri.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.

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.
