Chromosome: 14
Alteration at locus: Knockout
Monarch Initiative (Disease and Phenotype Associations): MGI:2177160
Gene Symbol: Atp12a (Mus musculus (mouse))
Name: ATPase, H+/K+ transporting, nongastric, alpha polypeptide
Synonyms: HKalpha2, Atp1al1, cHKA, ATPase H+K+-transporting, alpha 2
Chromosome: 14
Alteration at locus: Knockout
Monarch Initiative (Disease and Phenotype Associations): MGI:1926943
Genetic Alterations
The Atp12a gene was disrupted in 129/SvJ ES cells by inserting the neo gene into exon 20, thus disrupting critical transmembrane domains required for ion transport. 
Genotype Determination
ES Cell Line
Not specified
Phenotype

Homozygous: potassium wasting in colon when subjected to a low potassium or low sodium diet; impaired absorption of sodium in the colon via the epithelial sodium channel, which is critical in diarrhea states; loss of acidification of prostate fluid.

Heterozygous: Normal

Strain Development
Corrrectly targeted ES cells were intected into C57BL/6J blastocysts. Chimeric males bred with Black Swiss females yielded an animal carrying the disrupted cHKA gene in its germline. This mouse was bred to establish a colony on a NSA (Non Swiss Albino) background. This STOCK was further bred to BALB/c mice backcrossing an additional 10 generations making it congenic on the BALB/c background.

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.

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.

MMRRC Item # Description Distribution Fee / Unit (US $) Units Notes
036713-JAX-SPERM Cryo-preserved spermatozoa $437.00 / Non-Profit Aliquot Approximate quantity2
036713-JAX-RESUS Litter recovered from cryo-archive $2,022.00 / Non-Profit Litter Recovered litter1; additional fees for any special requests.

1 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.

2 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.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
